LCA - Snow RMM

Post by Aaron26 »

Hello,
I am trying to conduct a Latent Class Analysis. I have a sample of 516 participants who have score of 0-10 across 5 time periods. Missing scores were coded -1. Each time I input the time periods into the variable box of LCA I get the error, "invalid 'length' argument". I am unsure what this error means or how to correct it.

Any help would be really appreciated.

Thanks,

Aaron

Hi Aaron

Have you read "To get started" in the result screen? Variables must be coded with consecutive values from 1 to maximum number.

With Regards
Seol
