p_mat: Re-arranging a vector into parameter matrices

In ccgarch: Conditional Correlation GARCH models

Description

A utility function that re-arranges a vector of parameters into parameter matrices in the CC-GARCH(1,1) model.

Usage

   p.mat(para, model, ndim)

Arguments

para	a vector of parameters to be re-arranged into parameter matrices
model	a character string describing the model. "diagonal" for the diagonal model and "extended" for the extended (full ARCH and GARCH parameter matrices) model
ndim	the number of dimension of the model

Value

A list with components:

a	a vector of constants in the vector GARCH equation
A	an ARCH parameter matrix
B	a GARCH parameter matrix
R	a constant conditional correlation matrix
