simul_data_UniYX_binom: Data generating function for univariate binomial plsR models

In plsRglm: Partial Least Squares Regression for Generalized Linear Models

Data generating function for univariate binomial plsR models

Description

This function generates a single univariate binomial response value Y and a vector of explanatory variables (X_1,\ldots,X_{totdim}) drawn from a model with a given number of latent components.

Usage

simul_data_UniYX_binom(totdim, ncomp, link = "logit", offset = 0)

Arguments

totdim	Number of columns of the X vector (from ncomp to hardware limits)
ncomp	Number of latent components in the model (from 2 to 6)
link	Character specification of the link function in the mean model (mu). Currently, "logit", "probit", "cloglog", "cauchit", "log", "loglog" are supported. Alternatively, an object of class "link-glm" can be supplied.
offset	Offset on the linear scale

Details

This function should be combined with the replicate function to give rise to a larger dataset. The algorithm used is a modification of a port of the one described in the article of Li which is a multivariate generalization of the algorithm of Naes and Martens.

Value

vector

(Y,X_1,\ldots,X_{totdim})
