Thanks to Kit Baum, a new Stata package called -glst-
is available from SSC.
-glst- estimates linear regression model using generalized least squares
for trend estimation of summarized dose-response data. It differs from
variance weighted least squares (see vwls) in that glst estimates a
variance-covariance matrix of the beta coefficients, as proposed by
Greenland and Longnecker (1992).
