Subject: Generating a matrix of nominal correlation values in Crosstabs
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
When I need to run a factor analysis on dichotomous variables I
generally create a Kendall's tau correlation matrix, copy that into
syntax, and run the factor analysis from matrix input.
I am now dealing with a set of 7 variables that are quasi-ordinal, but
which for the sake of honest statistical procedure I want to treat as
Measures of association for nominal variables, such as Goodman-Kruskal's
Lambda and Cramer's V, are found under Crosstabs, rather than under
Correlate. So far, I have not found a way to generate matrix output from
Crosstabs, and I'm afraid that constructing a matrix from the piecemeal
output of Crosstabs will make it more likely for mistakes to creep in.
Does anyone know if it is possible to create a matrix of Lambda and/or
Cramer's V correlation values?
All the best,
