Dear Statalisters,
I am running a survival analysis. In this respect, does anyone know how we
can calculate the lambda and its standard error after we obtain the
following results?
Exponential regression -- accelerated failure-time form
No. of subjects = 40 Number of obs = 40
No. of failures = 32
Time at risk = 2059 LR chi2(1) = 4.35
Log likelihood = -38.159406 Prob > chi2 = 0.0371
-------------------------------------------------------------------
_t | Coef. Std. Err. z P>|z| [95% Conf. Interval]
---+----------------------------------------------------------------
group | 0.058095 .0266299 2.18 0.029 .0059 .1102
_cons | 1.193251 1.342353 0.89 0.374 -1.437 3.824
--------------------------------------------------------------------
I am not sure about this output. 1/lambda = exp(1.19+0.06*group)? However,
what about its standard error?
Thank you in advance.
Regards,
Tiago
