split_strata: Split each stratum into two parts

In splithalfr: Estimate Split-Half Reliabilities

Split each stratum into two parts

Description

Splits each element of strata into two parts. For more information about splitting options, and an extensive list of examples, see get_split_indexes_from_stratum.

Usage

split_strata(strata, ...)

Arguments

strata

(list) list of strata to split

...

Arguments passed on to get_split_indexes_from_stratum method (character) Splitting method. Note that first_second and odd_even splitting method will only deliver a valid split with default settings for other arguments (subsample_p = 1, split_p = 1, replace = TRUE) replace (logical) If FALSE, splits are constructed by sampling from stratum without replacement. If TRUE, stratum is sampled with replacement. split_p (numeric) Desired joint size of both parts, expressed as a proportion of the size of the subsampled stratum. If split_p is larger than 1, and careful is FALSE, then parts are automatically sampled with replacement subsample_p (numeric) Subsample a proportion of stratum to be used in the split. careful (boolean) If TRUE, stop with an error when called with arguments that may yield unexpected splits

Value

(list) A list with two elements, containing the first and second split of strata.

Examples

# Stratify a data frame, then split it odd-even
ds <- data.frame(condition = rep(c("a", "b"), each = 4), score = 1 : 8)
strata <- stratify(ds, ds$condition)
split_strata(strata, method = "odd_even")
