# cov_intraclass: Constructs a p-dimensional intraclass covariance matrix. In sortinghat: sortinghat

## Description

We define a p \times p intraclass covariance (correlation) matrix to be Σ = σ^2 (1 - ρ) J_p + ρ I_p, where -(p-1)^{-1} < ρ < 1, I_p is the p \times p identity matrix, and J_p denotes the p \times p matrix of ones.

## Usage

 1  cov_intraclass(p, rho, sigma2 = 1) 

## Arguments

 p the size of the covariance matrix rho the intraclass covariance (correlation) constant sigma2 the coefficient of the intraclass covariance matrix

## Value

an intraclass covariance matrix of size p \times p
