  • Stata WTP plots- delta method

    Hi,

    Silliest problem to be stuck at but here I am.

    I am trying to plot my WTP estimates with the confidence intervals all in 1 graph.
    WTP estimates calculated using delta method post mixlogit estimation.
    x1 x2 z1 z2 z3
    wtp 30.358541 12.174126 -182.59575 -68.798929 -41.01583
    ll 6.9271192 -2.5539443 -279.10688 -107.68705 -69.401824
    ul 53.789963 26.902197 -86.084627 -29.910802 -12.629837

    I also calculate using nlcom
    _nl_1: (_b[x1 ])/- (_b[ price ])
    choice Coefficient Std. err. z P>z [95% conf. interval]
    _nl_1 30.35854 11.95503 2.54 0.011 6.927119 53.78996

    Anyone have any suggestions?

    Thank you
    Magda
