Thanks as always to Kit Baum, a new version of the wridit package is now available for download from SSC. In Stata, use the ssc command to do this, or adoupdate if you already have an old version of wridit.

The wridit package is described as below on my website. In the new version, the fframe() option of the module fridit has a xvar(varname) option, allowing users to calculate foreign ridits for a variable with respect to a variable with a different name in the foreign frame, instead of with respect to a variable with the same name in a different frame.

Best wishes

Roger

TITLE
wridit: Generate weighted ridits

DESCRIPTION/AUTHOR(S)
wridit inputs a variable and generates its weighted ridits.
If no weights are provided, then all weights are assumed
equal to 1, so unweighted ridits are generated. Zero weights
are allowed, and imply that the ridits calculated for the
observations with zero weights will refer to the distribution
of weights in the observations with nonzero weights. fridit
inputs a variable and generates its weighted foreign ridits,
with respect to a distribution identified by the data in a
data frame.
