bdsvd.cov.sim: Covariance Matrix Simulation for BD-SVD

In bdsvd: Block Structure Detection Using Singular Vectors

Covariance Matrix Simulation for BD-SVD

Description

This function generates covariance matrices based on the simulation studies described in Bauer (2025).

Usage

bdsvd.cov.sim(p, b, design)

Arguments

p	Number of variables.
b	Number of blocks. Only required for simulation design "c" and "d".
design	Simulation design "a", "b", "c", or "d".

Value

A covariance matrix according to the chosen simulation design.
