I am estimating a path model with a poisson distributed (count) outcome, 5 mediators (1 categorical, 4 continuous) and 2 continuous IVs. The data is from a complex, stratified survey. I have three questions: 1) Do I interpret the StdYX for the paths to the count outcome identically to the StdYX for paths from the IVs to the mediators? 2) I am not getting fit statistics (CFI, RMSEA). Is it possible to get these in the context of a poisson regression? 3) Am I correct in specifying the binary mediator as such in the syntax (given that its both an IV and a DV?)
Thanks much for your help!!
STRATIFICATION is region; WEIGHT is gswgt3_2; CLUSTER is psuscid;
COUNT is perpw3; categorical is perpw2;
Type = complex missing ; integration = montecarlo;
MODEL: perpw3 on perpw2 h3ma4r impsex meandel expviol sexdrink; impsex on h3ma3r h3ma4r; meandel on h3ma3r h3ma4r; expviol on h3ma3r h3ma4r; sexdrink on h3ma3r h3ma4r ; perpw2 on h3ma3r h3ma4r; h3ma3r; h3mar4;
1. Only the metric of the dependent variable is different. 2. No. These test statistics are available only when the means, variance, and covariances are sufficient statistics for model estimation. 3. Yes. Note that when it is a dependent variable it is treated as binary, but when it is an independent variable is is treated as continuous.
