rdasim2: Generate simulated data for Ridge Redundancy Analysis (RDA).
Description
The rdasim2 function generates simulated data for Ridge Redundancy Analysis (RDA) with adjustable signal-to-noise ratio and covariance structure for X. The data matrix Y is created by a low-rank model, where the rank is set by the product of two matrices A and C corresponding to the number of latent variables (k). The function allows control over the signal-to-noise ratio (s2n) and off-diagonal elements of the covariance matrix for X (xofd). It returns a list containing the matrices X, Y, the regression coefficient matrix B (obtained as the product of A and C), and the error matrix E.
Usage
rdasim2(n, p, q, k, s2n = 5, xofd = 0)
Value
A list containing matrices X, Y, B, E.
Arguments
n

p
The number of variables of X.
q
The number of variables of Y.
k
The number of latent variables.
s2n
The numeric parameter of signal to noise ratio, default value is 5.
xofd
The numeric parameter of the off-diagnal elements of covariance matrix of X, default is 0.
