Can I see Log-likelihood values for two-step clustering in SPSS?

Cross Validated Asked by Yauheniya Volchok on December 18, 2021

I need to compare Two-step clustering with latent class analysis. As LCA is not possible in SPSS I did it in R, however, 2-step clustering in R is quite challenging, so I did it in SPSS. To compare it I need different measures including the values of log-likelihood. The question is can I obtain it somehow from the two-cluster analysis in SPSS?

One Answer

SPSS Statistics TWOSTEP CLUSTER will not directly output a log-likelihood, only AIC or BIC when doing automatic selection of the number of clusters, so you'd have to dig into the formulas in the algorithms in order to manually calculate it.
