Typo in documentation

[ellessenne]

Hi,
I noticed that in the documentation for the covariance option there is a reference to independent (where it should be diagonal), likely here:

stmixed/stmixed/stmixed.sthlp

Line 110 in 9f85615

{synopt :{opt ind:ependent}}one variance parameter per random effect,

As expected, this fails:

. use http://fmwww.bc.edu/repec/bocode/s/stmixed_example1, clear

. stset stime, f(event=1)

Survival-time data settings

         Failure event: event==1
Observed time interval: (0, stime]
     Exit on or before: failure

--------------------------------------------------------------------------
      6,000  total observations
          0  exclusions
--------------------------------------------------------------------------
      6,000  observations remaining, representing
      3,427  failures in single-record/single-failure data

                                                At risk from t =         0
                                     Earliest observed entry t =         0
                                          Last observed exit t =  1.985816

. stmixed x1 x2 || centre: , dist(weibull) covariance(independent)
Random effect M1: Intercept at level centre
option independent not allowed
r(198);

Hope this helps, it should be a quick fix!
