2Reflect: As we learned this week, “Logistic Regression is part of a family of techniques designed to analyze the relationship between an interval-level independent variable and a categorical dependent variable, a dependent variable measured by nominal or ordinal values” (Pollack, 2016, p. 215). This powerful statistical tool enables researchers to predict the probability of an occurrence of an event and is particularly helpful when the relationship between the dependent variable and independent variable(s) is nonlinear. We also learned how to conduct maximum likelihood estimations and multiple regressions. In addition, we investigated how probabilities can be used to interpret logistic regression results. Our methodological tool bag is full, and now we need to practice using these political science tools so that they become more familiar and easier to use.
Write: In your initial post of at least 250 words, using Exercise 1 on pages 239-240, complete the following:
First, fill in the blank: The logistic regression coefficient tells us that, for each one-unit increase in the party identification scale, the logged odds of a pro-control opinion increases by .506. Turn your attention to the odds scale, Exp(b). Recall that higher values of party identification are more Democratic and lower values are less Democratic. This coefficient says that an individual at one value of party identification is times as likely to be pro-control as an individual at the next-lower level of party identification.
Then, use the value of Exp(b) to compute a percentage change in the odds. According to your calculations, each unit increase in party identification, from less Democratic to more Democratic, increases the odds of being pro-control by how much?
State the null hypothesis for this relationship.
Finally, explain what the inferential decision is: reject the null hypothesis or do not reject the null hypothesis.
