Generalized Least Squares for Trend Estimation of Summarized Dose–response Data
Nicola Orsini, Rino Bellocco, Sander Greenland- Mathematics (miscellaneous)
This paper presents a command, glst, for trend estimation across different exposure levels for either single or multiple summarized case–control, incidence-rate, and cumulative incidence data. This approach is based on constructing an approximate covariance estimate for the log relative risks and estimating a corrected linear trend using generalized least squares. For trend analysis of multiple studies, glst can estimate fixed- and random-effects metaregression models.
