    I have some questions I'd like to ask the experts.
    1. I read some articles about methods for handling longitude data, like The SEM approach to longitude data analysis using Calis procedure by An and Yung, but they didn't use path analysis. If I want to use path analysis to analyze longitude data, how should I go about it?"
    2.Additionally, my variables include both binary and continuous types. How should I handle this? I find some way that use METHOD=ML to deal with it, is that correct? Basically, I think the outcome should be a little bit like Logistic Regression.
    Bottom part is my code, but this is not longitude data, and I have no idea that this way can deal with binary variables (TNT and HF is binary).
    For short the parts, I delete some similar code.
    proc calis covariance outmodel=_eqparms_ method = MLM ;
    lineqs
    TNT = pTNTDM DM +pTNTLVEF LVEF+e_TNT,
    HF=pHFTNT TNT +pHFbmi bmi+pHFDM DM+e_HF;
    var TnT tempme bmi dm age lvef egfr msbp edvi_di HF;
    run;
    proc print data=_eqparms_;
    run;
