resample_helpers: Internal Helpers for Resampling of Summary Statistics

Description

These functions support the construction of intervals for descriptive statistics computed from observed or simulated data. They are used internally by stats_resample_dm() methods.

Usage

stats_resample_wrapper(
  obs_data_split,
  one_set_idxs = NULL,
  type,
  b_coding,
  ...
)
resample_assemble(resample_list, level, original)

Value

stats_resample_wrapper() returns a single stats_dm object for one sample.
resample_assemble() returns a stats_dm object containing the lower and upper interval bounds along with the original estimate.

Arguments

obs_data_split: a named list of data.frames, containing a single set of observed data, splitted by condition
one_set_idxs: a named list of numeric vectors. Each entry contains indices to shuffle the data.frames in obs_data_split. Default NULL keeps obs_data_split as is.
type: a character, passed to calc_stats_pred_obs().
b_coding: a list with boundary coding information, , required to wrangle rts to match with calc_stats_pred_obs().
...: additional arguments passed to calc_stats_pred_obs().
resample_list: a list of statistics returned by calls to stats_resample_wrapper().
level: a numeric between 0 and 1, controlling the width of the interval.
original: a stats_dm object representing the statistic computed from the original data set or model prediction.

Details

stats_resample_wrapper() wraps a call to calc_stats_pred_obs() for use in resampling.

resample_assemble() takes a list of resampled statistics and the original statistic, and computes lower and upper bounds based on the requested level. It returns a stats_dm object with an added Estimate column.
