Subject | st: New package -dsweight- on SSC |
Date | Fri, 20 Jan 2012 20:15:55 +0000 |
The -dsweight- package is described as below on my website. It calculates direct-standardization weights, which the user can then input as -pweights- to estimation commands to estimate directly-standardized ragression or rank parameters.

A direct standardization weight is defined as a ratio between the frequency of a combination of values of standardization variables in a target standard population and the frequency of the same combination of values of standardization variables in the sample or group. The standard target population may be the full sample, or a by-group defined by a combination of values of by-variables, or it may be defined using a dataset with 1 observation per combination of the group variables, and data on the frequencies of these combinations in the standard target population.
