Main Functions

This package was developed to introduce helper functions for common tasks in the class's assignments. These functions save us some time and energy. Helper functions currently include:

• or — a function to calculate odds ratios and confidence intervals for a logistic regression model
• chi_log — a function to calculate the Pearson's goodness of fit to a logistic regression model
• predict_percent — a function to calculate an accuracy percentage for a logistic regression model based off of predicted probabilities
• fences — a function to calculate the upper and lower fences of a continuous variable
• compare_models — a function to compare output from multiple models
• deviance_aic — a function that compares only null deviance, residual deviance, and AIC between multiple models
