Dear team: There is an implementation of FIML estimation in the context of single equation regression in Gretl?. I have seen that Stata and other R functions performs this kind of analysis using SEM capabilities as a workaround to deal with missing data. Also I have found that there is an implementation in Gretl for the case of Systems of Equations.... Thanks in advance and sorry for any inconvenience. José Perles University of Alicante
