fn_se_stdR Documentation

Calcualte the standard error of the standard deviation

Description

The standard deviation is calculated as the square root of the diagonal of the variance coavariance matrix of your random parameters. The variance- covariance matrix is calculated using the estimated lower Cholesky matrix.

Usage

fn_se_std(a, L, lambda)

Arguments

a

An integer indicating the row position of the random parameter in the asymptotic variance-covariance matrix

L

The lower cholesky matrix

lambda

The asymptotic variance covariance matrix

Value

A vector of standard errors
