pm: Constructor for parameter matrix

In espenmei/svcmr: Structured Variance Component Models

Constructor for parameter matrix

Description

Creates an object of type pm used to represent parameters in a model.

Usage

pm(
  nrow = NA,
  ncol = NA,
  labels = character(),
  free = FALSE,
  values = NA,
  name = NA
)

Arguments

nrow	Number of matrix rows.
ncol	Number of matrix columns.
labels	Vector/matrix with parameter labels. Equal characters defines equality constraints.
free	Vector or matrix of logical values defining parameters free or not.
values	Vector/matrix with parameter values. Values for free parameters are used as starting values for optimization and values for fixed parameters are constant during optimization.
name	Character giving name to model object. Used to reference the parameter matrix in computations.

Value

An object of class pm.

Examples

library(svcm)
S <- pm(nrow = 2, ncol = 2,
        labels = c("s11", "s12", "s12", "s22"),
        values = c(2, 1, 1, 2),
        free = TRUE,
        name = "S")
