WebQuestion: This question involves logistic regression analysis of the Pima data set in R on risk factors for diabetes among Pima women. Your training and holding data sets will be subsets of the Pima.tr and Pima te data sets in the library MASS. The binary response variable is type (type=Yes for Diabetes, type=No for no diabetes). WebLogistic regression, also called a logit model, is used to model dichotomous outcome variables. In the logit model the log odds of the outcome is modeled as a linear combination of the predictor variables. Please note: The purpose of this page is to show how to use various data analysis commands. WebLogistic regression is a data analysis technique that uses mathematics to find the relationships between two data factors. It then uses this relationship to predict the value of one of those factors based on the other. The prediction usually has a finite number of outcomes, like yes or no. cyclops team
