iqnn_cv_predict: Cross Validated predictions for iqnn models

In kmaurer/iqbin: Iterative Quantile Binning

Description

Cross-validate an iqnn specification using k-fold scheme on given data

Usage

iqnn_cv_predict(data, y, mod_type = "reg", bin_cols, nbins,
  jit = rep(0, length(bin_cols)), stretch = FALSE, tol = rep(0,
  length(bin_cols)), strict = FALSE, cv_k = 10)

Arguments

data	Data frame containing the response variable and numeric input variables from the training data
y	Name of response variable column
mod_type	Depends on response variables type: "reg" creates iqnn-regression for predicting numeric values, "class" creates iqnn-classifier for predicting categorical values
bin_cols	vector of column names of variables to iteratively bin, ordered first to last
nbins	vector of number of bins per step of iterative binning, ordered first to last
jit	vector of margins for uniform jitter to each dimension to create seperability of tied obs due to finite precision
stretch	TRUE/FALSE if will bins be given tolerance buffer
tol	vector of tolerance values to stretch each dimension for future binning
strict	TRUE/FALSE: If TRUE Observations must fall within existing bins to be assigned; if FALSE the outer bins in each dimension are unbounded to allow outlying values to be assigned.
cv_k	integer specifying number of folds

Value

cross validated predicted responses for all observations in data
