Thanks once again to Kit Baum, a new version of the -dsweight- package is now available for download from SSC. In Stata, use the -ssc- command to do this, or -adoupdate- if the user already has an old version of -dsweight-.

The -dsweight- package is described as below on my website. The new version adds a second module -scdsweight- for calculating scenario direct standardization weights, for use with the recently-updated -scsomersd- package, which you can also download from SSC. These scenario direct standardization weights can be used with -scsomersd- to calculate population attributable risks. It also adds a few additional examples in the on-line help, illustrating how direct standardization weights can be used with rank statistics by inputting them as pweights to modules of the -somersd- package (also downloadable from SSC).

Best wishes

Roger

TITLE
      dsweight: Generate direct standardization weights

DESCRIPTION/AUTHOR(S)
      dsweight generates direct standardization weights for input as
      pweights to estimation commands, standardizing the joint
      distribution of a list of standardization variables to a standard
      target population, possibly within groups defined by value
      combinations of a list of group variables.  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.
