st: 'combine': new SSC module

[Philip Jones <pjones8@uwo.ca>]

Thanks to Kit Baum, a new module is available in the SSC archives.

'combine' is meant to be used by analysts performing meta-analysis whereupon it is
sometimes necessary to combine size (n) , mean, and SD from two groups (for example,
two intervention groups). The Cochrane Collaboration provides a formula for this
calculation in its handbook, but it is cumbersome to perform using a calculator, or by
hand. combine allows this calculation to be done quickly.

To install, type:

ssc install combine

Please send feedback by email or on Statalist.

Have a great weekend,

Phil
