In AndrewKostandy/MLtoolkit: Functions to Help with Machine Learning & Feature Engineering Tasks

Description

Get the proportion of each combination of two predictors' levels having each outcome level as well as the lower and higher ends of the 95% confidence interval of the proportion.

Usage

get_prop2(data, predictor1, predictor2, outcome)

Arguments

data	The dataframe containing the predictor and outcome variables.
predictor1	The first predictor variable name.
predictor2	The second predictor variable name.
outcome	The outcome variable name.

Value

Returns a dataframe that includes the following columns:

predictor1	The first predictor variable levels.
predictor2	The second predictor variable levels.
outcome	The outcome variable levels.
n	The number of observations for each combination of levels of both predictors and the outcome.
sum_n	The total number of observations for each combination of levels of both predictors.
prop	The proportion of each combination of both predictor levels having each outcome level.
low_95ci	The lower end of the 95% confidence interval of the proportion.
high_95ci	The upper end of the 95% confidence interval of the proportion.
