Now we can relate the odds for males and females and the output from the logistic regression. The intercept of -1. Using the odds we calculated above for males, we can confirm this: log(. The coefficient for female is the log of odds ratio between the female group and male group: log(1.
So we can get the odds ratio by exponentiating the coefficient for female. Most statistical packages display both the raw regression coefficients and the exponentiated coefficients for logistic regression models.
The table below is created by Stata. In other words, the odds of being in an honors class when the math score is zero is exp(-9. These odds are very low, but if we look at the distribution of the variable math, we will see that no one in the sample has math score lower than 30. In fact, all the test scores in the data set were standardized around mean of 50 and standard deviation of 10. So the intercept in this model corresponds to the log odds of being in an honors class when math is at the hypothetical value of zero.
How do we interpret the coefficient for math. We will use 54. Then the conditional logit of being in an honors class when the math score is held at 54 isWe can examine the effect of a one-unit increase in math score. When the math score is held at 55, the conditional logit of being in an honors class isWe can say now that the coefficient for math is the difference in the log odds.
In other words, for a one-unit increase in the math score, the expected change in log odds is. Can we translate this change in log odds to the change in odds.
Recall that logarithm converts multiplication and division to addition and subtraction. Its inverse, the exponentiation converts addition and subtraction back to multiplication and division. Applying such a model to our example dataset, each estimated coefficient is the expected change in the log odds of being in an honors class for a unit increase in the corresponding predictor variable holding the other predictor variables constant at certain value. Each exponentiated coefficient is the ratio of two odds, or the change in odds in the multiplicative scale for a unit increase in the corresponding predictor variable holding other variables at certain value.
Here is an example. In all the previous examples, we have said that the regression coefficient of a variable corresponds to the change in log odds and its exponentiated form corresponds to the odds ratio. This is only true when our model does not have any interaction terms. The interpretation of the regression coefficients become more involved.
In this simple example where we examine the interaction of a binary variable and a continuous variable, we can think that we actually have two equations: one for males and one for females. Now we can map the logistic regression output to these two equations. More explicitly, we can say that for male students, a one-unit increase in math score yields a change in log odds of 0.
On the other hand, for the female students, a one-unit increase in math score yields a change in log odds of (.
In terms of odds ratios, we can say that for male students, the odds ratio is exp(. The ratio of these two odds ratios (female over male) turns out to be the exponentiated coefficient for the interaction term of female by math: 1.

Introduction When a binary outcome variable is modeled using logistic regression, it is assumed that the logit transformation of the outcome variable has a linear relationship with the predictor variables. From probability to odds to log of odds Everything starts with the concept of probability.As a result, large traditional oil enterprises stopped exploring new reserves.
These companies include Exxon-Mobil, BP, Chevron and Royal Dutch Shell. It was cheaper for them to buy out the less efficient, shale oil companies.
That's because less-efficient shale producers either cut back or were bought. That reduced supply by around 10 percent, creating a boom and bust in U. The second reason for recent volatility is foreign exchange traders. They drove up the value of the dollar by 25 percent in 2014 and 2015. All oil transactions are paid in dollars. The strong dollar helped cause some of the 70 percent declines in the price of petroleum for exporting countries.
Most oil-exporting countries peg their currencies to the dollar. Therefore, a 25 percent rise in the dollar offsets a 25 percent drop in oil prices. Global uncertainty is one factor that makes the U. Since December 2016, the dollar's value has been falling according to the DXY interactive chart. On December 11, 2016, the USDX was 102.
In early 2017, hedge funds began shorting the dollar as Europe's economy improved. As the euro rose, the dollar fell. By September 15, 2017, it had fallen to 91. Third, OPEC didn't reduce output to put a floor under prices until November 30, 2016. Its members agreed to cut production by 1. That lowered production to 32. But the so-called cut was higher than its 2015 average of 32. Prices began rising right after the OPEC announcement. On May 25, 2017, OPEC extended these cuts through March 2018.
The EIA forecasts OPEC will produce 32.
But both figures are still higher than the 2015 average before the "cuts. In 2014, it abandoned this policy. Saudi Arabia, OPEC's biggest contributor, lowered its price to its largest customers in October 2014. It did not want to lose market share to U. These two countries' rivalry stems from the conflict between the Sunni and Shiite branches of Islam.
Iran promised to double its oil exports to 2. The nuclear peace treaty allowed Saudi Arabia's biggest rival to sell oil in 2016.

Just be sure your teen is behaving appropriately in both the real and online worlds. Many teens need to be reminded that a platform's privacy settings do not make things actually "private" and that images, thoughts, and behaviors teens share online will instantly become a part of their digital footprint indefinitely. Keep lines of communication open and let them know you're there if they have questions or concerns.
Warn children about the importance of privacy and the dangers of predators and sexting. Teens need to know that once content is shared with others, they will not be able to delete or remove it completely, and includes texting of inappropriate pictures. They may also not know about or choose not to use privacy settings, and they need to be warned that sex offenders often use social networking, chat rooms, e-mail, and online gaming to contact and exploit children.
Remember: Kids will be kids. Kids will make mistakes using media. Try to handle errors with empathy and turn a mistake into a teachable moment. But some indiscretions, such as sexting, bullying, or posting self-harm images, may be a red flag that hints at trouble ahead. Parents must observe carefully their children's behaviors and, if needed, enlist supportive professional help, including the family pediatrician. Media and digital devices are an integral part of our world today.
The benefits of these devices, if used moderately and appropriately, can be great. But, research has shown that face-to-face time with family, friends, and teachers plays a pivotal and even more important role in promoting children's learning and healthy development. Keep the face-to-face up front, and don't let it get lost behind a stream of media and tech.
Editor's Note: The tips above were written from two AAP policies, "Media Use in School-Aged Children and Adolescents" and "Media and Young Minds," and the technical report entitled "Children and Adolescents and Digital Media," which were published in the November 2016 edition of Pediatrics.
They were also drawn from the proceedings of the AAP Sponsored Growing Up Digital: Media Research Symposium, a gathering of media experts, researchers and pediatricians held in 2015 to address new developments in research and media and their impact on children.

There may be variations in treatment that your pediatrician may recommend based on individual facts and circumstances. When reviewing business headlines and news stories it can be difficult to decide which topic is mentioned more often -- data analytics or social media.
This can be even more frustrating if you, as an entrepreneur, are trying to decide where to focus your limited time, money, and energy to help give your business an edge. Making adoption of social media strategies even more difficult is the fact that this field changes so rapidly.
Many of the negative reactions to social media are usually based on an understanding of social media that is limited to snarky Tweets, sharing funny cat videos, and using different filters on Snapchat. This understanding, however, provides only an incomplete view of what social media can do for you and your business.
As I am sure you have seen, however, there are many different types of social media you could use for your business. It is also important to recognize that while most social media tools are free to use, there are certain products and services that provide a base level of services for free, but charge for more sophisticated services.
Fortunately there are some common sense, and budget friendly, things you can do to increase the impact of your social media bucks. For example, if you own a bakery, work in retail, or own a floral business on the side, Pinterest might be the best way to showcase your business. Focusing on showcasing your business in the best possible light always makes sense, and is no different for social media utilization.
Both platforms, especially Facebook, have incredibly large platforms that can boost the reach of your business without costing you an arm and a leg. After you have selected your social media platform of choice, it is important to put together a plan (even a simple plan) on how often you will update, post, or otherwise engage on social media.
Chambers of commerce, small business development centers, and other local resources are just a few of the groups that you should be sure to engage with, and they are always happy to hear from interested parties. Especially for social media, where content is posted and shared on a minute-by-minute basis, it is even easier to adapt your approach to your customers and professional associations.
Social media is a potentially great tool, should be used to help build and expand your business, and can be implemented without breaking the bank. That said, it is impossible to overlook the benefits of building a social media strategy, engaging with customers, and expanding the reach of your business in an increasingly digital environment. Approaching social media from a business perspective, setting up a plan, and selecting the right strategy for your business can set your business up for an effective social media campaign.
