Logistic regression test - Study guides, Class notes & Summaries

Logistic Regression - Commonly used for modeling binary response data. The response variable is a binary variable, and thus, not normally distributed. In logistic regression, we model the probability of a success, not the response variable. In this model, we do not have an error term g-function - We link the probability of success to the predicting variables using the g link function. The g function is the s-shape function that models the probability of success with respect to the predict...

This summary contains all the lecture notes of the course statistics 1 from year 1 of Psychology and Pedagogy. I included the text on the slides plus the comments of the professor so that you have a perfect overview of all the material for the exam. The book was really not needed for this exam because I got an 8 with only studying the lecture notes.

What is cooks distance used for? - correct answer It measures how much all of the values in the regression model change with the ith observation is removed. Basically its a test for outliers Rule of thumb: D denotes cooks distance, if D is > 4/n OR D > 1 or any large D then it may be an outlier and should be removed. If the normality assumption does not hold, we can pursue a transformation in the response variable. T/F - correct answer ...

WGU STatistics Test Questions And Answers In a standard 52-card deck, where each card is assigned a numeric value, the mean of the 52 cards is 7.0 with a standard deviation of 3.742. To test if a representative sample can be attained, the deck is shuffled and 13 cards are randomly drawn, one at a time. Each card is recorded and then returned randomly to the deck before the next card is drawn. This process of drawing 13 random cards is repeated a total of 20 times, and the mean and standard d...
