  • plotting Nelson–Aalen cumulative hazard estimates

    hi i'm trying to learn how to calculate transition probailities for a 3 state markov model

    I'm following prof crowther notes, really useful
    https://www.stata.com/meeting/italy1...8_Crowther.pdf

    However, in Figure 4 (slide 30) he shows 3 graphs comparing Nelson-Aalen fits which has a blue line (model) and red line (estimate) , which is normally generated from

    Code:
    sts graph, na
    However, in his case he doesn't demonstrate the code used.

    Using his code and attempted to plot N-A estimates, I only produce the actual model fit and not the red line, which I assume is the estimate

    How can I modify the code below to generate similar graphs he produced in one panel ?

    Code:
    //RP model with 3 degrees of freedom 
    stpm2 if _trans1==1, scale(h) df(3)
    sts graph, na
    
    //Weibull model 
    streg if _trans2==1, distribution(weibull)
    
    //RP model with 3 degrees of freedom
    stpm2 if _trans3==1, scale(h) df(3)
Working...
