It's indeed difficult to add to Martin's diagnosis of the first error because, although meticulous about other details, Victor omitted to specify exactly what he typed. But the graph call in question graph z psi if z<2.5&z>-2.5, yline(-1.96, 0, 1.96) xlab ylab xline(`gestl', `gest', `gestu') `options' is under Stata 7 syntax (in Stata 8 up documented under -graph7-). Here `options' is, or should be, whatever graph options Victor typed on his command line. Any attempt to add options for the graphics introduced in Stata 8 is likely to produce an error message. Nick n.j.cox@durham.ac.uk Martin Weiss The second error occurs because -gesttowb- is looking for results left behind by a Weibull estimation. If you have not run this estimation previously, the macros that -gesttowb- is trying to multiply do not exist. The example code "geststb.do" delivered with the package runs without a hitch for me, btw, and executes -gesttowb- repeatedly. The first error does have something to do with the -graph- command on line 304 of -stgest.ado-, though the problem is difficult to track down. Victor Mauricio Herrera I wonder if anyone could shed light on the following. I consistently get two error messages while using the stgest command (Stata Journal 2002, 2(2):164-182) in Stata/MP 11.0. The first one happens after the causal survival ratio is reported: "Note - these estimates should be confirmed with an interval bisection search by omitting the step option option ( not allowed r(198);" I guess this has something to do with the instructions to graph the psi-by-z graph. The second error occurs when using gesttowb: gesttowb g-estimated hazard ratio *: operator invalid r(198); My versions of these programs are: which gesttowb c:\ado\plus\g\gesttowb.ado *! Version 1.0 (SJ2-2: st0014) which stgest c:\ado\plus\s\stgest.ado *! version 5.5 JACS/KT g-estimation, June 2002 (SJ2-2: st0014) * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
