Title: standard error of conditional covariances/correlations in multidimensional run?
Post by: furonggao on April 24, 2020, 03:15:10 PM
Hi,

Is there any way to calculate the standard error of the covariances/correlations of the dimensions? In the .shw file, only the variances' standard errors are shown, but not the covariances'. Thanks!

Sincerely,
Furong Gao

you can extract the full error variance-covariance matrix and include in your Show file. See here:

https://conquestmanual.netlify.app/s4-00.html#show (https://conquestmanual.netlify.app/s4-00.html#show)

You need to:

1. use empirical errors
Code: [Select]
estimate ! ... stderr = empirical ...;This is the default behaviour if you do not specify the stderr option.
2. add the option to your show command
Code: [Select]
show ! ... tables = 10 ...; Table 10 is the error variance-covariance matrix
