st: Meta-analysis of AUC curves developed using different type of regression models

[Etan Lakam <etan.lakam@googlemail.com>]

Dear Listers,

I have a series of studies of prediction  of an outcome , in which the
area under the curve (AUC) or C-statistic was estimated using
different variables and different types of regression models (Weibull
and Logistic), and I would like to combine the AUCs in a
meta-analysis.

I have two questions:

1- Which Stata command I use to combine the AUCs if I have these
estimates and their standard error or 95%CI confidence intervals?   I
really can't get my head around this.


2- Is such a meta-analysis a sensible thing to do given the
heterogeneity linked to  the differences in regression models (Weibull
and logistic) used for model developement and the differences in
variables used for prediction across studies and?


Many thanks,


Etan

PS: Any documentation on the topic (metanalysis of AUCs curves) will
also be welcome.
