fn_1: Helper function fn_1
In edsandorf/cmdlR: Choice Modeling in R
fn_1 R Documentation
Helper function fn_1
Description
Helper function to calculate the standard errors of standard deviations and
correlations from a MIXL model. Together, all the helper functions and the
four functions fn_se_var, fn_se_cov,
fn_se_corr and fn_se_std, is an application
of the Delta method. The helper functions are for internal use only and are
not exported.
Usage
fn_1(a, L)
Arguments
a
An integer indicating the row position of the random parameter in the
asymptotic variance-covariance matrix
L
The lower cholesky matrix
