Check Pilot set options

Description

Check Pilot set options

Usage

check_pilot_set_options(
  pilot_fraction,
  pilot_size,
  group_by_covariates,
  data,
  n_c
)

Arguments

pilot_fraction	numeric between 0 and 1 giving the proportion of controls to be allotted for building the prognostic score (default = 0.1)
pilot_size	alternative to pilot_fraction. Approximate number of observations to be used in pilot set. Note that the actual pilot set size returned may not be exactly pilot_size if group_by_covariates is specified because balancing by covariates may result in deviations from desired size. If pilot_size is specified, pilot_fraction is ignored.
group_by_covariates	character vector giving the names of covariates to be grouped by (optional). If specified, the pilot set will be sampled in a stratified manner, so that the composition of the pilot set reflects the composition of the whole data set in terms of these covariates. The specified covariates must be categorical.
data	data.frame with observations as rows, features as columns
n_c	number of control observations in data

Value

nothing
