ppi_samplesize_effect: Simulate Effect of Sample Size on Projection Pursuit Index...

In spinebil: Investigating New Projection Pursuit Index Functions

Simulate Effect of Sample Size on Projection Pursuit Index Under Gaussian Noise

Description

For a given index function, simulates how the index behaves across a range of sample sizes when applied to pairs of standard normal noise.

Usage

ppi_samplesize_effect(index_fun, n_sim = 100)

Arguments

index_fun	A function taking two numeric vectors (x, y) and returning a scalar index.
n_sim	Integer. Number of simulations per sample size. Default is 100.

Value

A tibble with:

• sample_size: sample size used for each simulation block

• percentile95: 95th percentile of the index values over simulations

Examples

## Not run: 
ppi_samplesize_effect(scag_index("stringy"), n_sim = 3)

## End(Not run)
