en_kfold_accuracy function

Description

This function calculates the cross validated accuracy of an enr model

Usage

en_kfold_accuracy(
  ddata,
  response_var,
  mod_alpha,
  mod_lambda = NULL,
  iter = 100,
  k = 10,
  seed = 123,
  loo = FALSE,
  eq_wt = FALSE,
  type_meas = "deviance",
  lr_cutoff = c(0.5)
)

Arguments

ddata	data frame containing the data to be summarized
response_var	vector of variable names for the variables that are t be summarized. all variables must be present in the data frame
mod_alpha	optional class variable to cross with the independent variables. this is is typically presented as a text (e.g. data$variable)vector of names to change the rows in column 1 to. This is typically what you want the individual variables that the rows represent called in the table. this must be the same length as vars. default is NULL which simply returns vars.
mod_lambda	vector of boolean values indicating whether the variable should be 'fp' (true) or custom/msd (false). default is true
iter	a vector of the first function to use (i.e. outside the parentheses) if fp='FALSE'. default is 'mean'. if supplying different functions be sure to quote e.g. "IQR"
k	a vector of the second function to use (i.e. inside the parentheses) if fp='FALSE'. default is 'sd'. if supplying different functions be sure to quote e.g. "IQR"
seed	a vector of variable names to use in the table. If left as null the table will contain the variable names as listed in the data frame
loo	boolean value indicating whether the variable name should be added to the table (TRUE) or not (FALSE). default is TRUE
eq_wt	boolean indicating whether duplicate values of the variable name should be removed (TRUE) or included (FALSE). default is TRUE
type_meas	boolean indicating if the n value used after na removal should be displayed in non fp cases. this will only appear when fp=FASLE. default is TRUE
lr_cutoff	boolean indicating if a 'total' column should be added to the data frame. default is TRUE
