compute_subsample: Compute Subsample of Data by Block

In FARS: Factor-Augmented Regression Scenarios

Compute Subsample of Data by Block

Description

Selects a random subset of columns within each block of the input data matrix.

Usage

compute_subsample(data, block_ind, n, sample_size = 1, seed = NULL)

Arguments

data	A numeric matrix or data frame containing the original data.
block_ind	Integer vector specifying the end indices of each block. If NULL, assumes a single block spanning all columns.
n	Integer specifying the number of blocks.
sample_size	Numeric between 0 and 1 specifying the proportion of columns to sample within each block. Defaults to 1 (all columns).
seed	Optional integer. Seed for reproducibility of the column sampling. If NULL, sampling is random.

Value

A list with two elements:

sample_data

A numeric matrix combining the sampled columns from all blocks.

sample_block_ind

An integer vector containing the indices corresponding to the sampled data.
