DescriptionData from southern hardwood stands in East Texas were used to estimate parameters for d.b.h.-height equations. Mixed model estimation methods were used, so that the stand from which a tree was sampled was considered a random effect. This makes it possible to calibrate these equations using data collected in a local stand of interest, by using d.b.h. and total height measurements from a particular stand to estimate random parameters appropriate for that stand. The calibrated d.b.h.-height equation provides an improved fit for the conditions in a particular stand with less data than would be required to estimate parameters in a new d.b.h.-height equation. These data were obtained from the western portion of the natural range for most southern hardwood species, where relatively little information concerning d.b.h.-height relationships exists for southern hardwoods.
