rgs_for_logistic {RGS} | R Documentation |
Main function for logistic regression analysis
Description
This function performs logistic regression analysis to identify optimal cutoffs and evaluate the model. Users are required to create and set the datadist option globally before using this function.
Usage
rgs_for_logistic(my_data, u_variables, covariates)
Arguments
my_data |
A dataframe containing the data. |
u_variables |
A character vector specifying the names of the U-shaped variables. |
covariates |
A character vector specifying the names of the covariates. |
Value
A dataframe containing the best combination of cutoffs and associated AIC value.
Examples
library(rms)
data_path <- system.file("extdata", "logistic_data.csv", package = "RGS")
my_data <- read.csv(data_path)
# Define variables
u_variables <- c("u1", "u2")
covariates <- c("l1", "c1")
# create and set the datadist option globally
dd <- datadist(my_data)
options(datadist = "dd")
