Constructor for ftmlm Objects

ftmlm.Rd

Creates an instance of the ftmlm class, initializing it with specific matrices necessary for the flexible transfer model calculations. This function is typically called internally within higher-level functions that prepare data and perform model fitting.

Usage

ftmlm(XtX, Xty, s = 0, n = NA_real_, yty = NA_real_, y_mean = NA_real_)

Arguments

XtX

A numeric matrix representing the cross product of predictors.

Xty

A numeric matrix representing the cross product of predictors and outcomes.

s

A numeric value representing the optimal Ridge penalty from cross-validation (if available).

n

A numeric value representing the number of observations.

yty

A numeric value representing the sum of squared responses.

y_mean

A numeric value representing the mean of the outcome variable.

Value

An object of class ftmlm.

Examples

if (FALSE) { # \dontrun{
  XtX <- matrix(rnorm(100), 10, 10)
  Xty <- matrix(rnorm(10), 10, 1)
  model <- ftmlm(XtX, Xty)
} # }
