A new extension command, STATS SURVREG
has been posted to the Extension Commands collection of the SPSS Community
website (www.ibm.com/developerworks/spssdevcentral).
Click on Downloads for SPSS Statistics and then Extension Commands
to access it. The procedure estimates survival regression for left,
right, interval, and counting censoring for these distributions: Weibull,
exponential, Gaussian, logistic, lognormal, loglogistic, and t. It
can do Tobit regression as well, although there is another extension command,
SPSSINC TOBIT REGR, dedicated to that model.
It can save a dataset with a variety
of residuals, predicted values, and diagnostic measures.
The package requires the R Essentials.
It has been tested mainly with Statistics 21 but is expected to work
with versions back to 18.
We hope that you will find this package
useful.
