Bootstrap prediction and tolerance intervals for the Weibull regression model with censored data

Creator:

Abdelhafez, Mohamed Elwy Mahran

Abstract:

The problems of constructing prediction and tolerance intervals were considered for Weibull regression models. On the extreme value distribution scale, the models have the linear form y = Xβ + σ z , =NM where y is the transformed random response vector, X is the nxq matrix containing values of...

Weibull diameter distribution models for managed stands of Douglas-fir in Washington and Oregon

Creator:

Eng, Helge

Abstract:

The two-parameter Weibull function was used to predict forest stand diameter distributions and growth. Diameter distribution models were developed for even-aged Douglas-fir stands, 20 to 40 years old, in Oregon and Washington. In order to test if the two-parameter Weibull function can adequately describe the diameter distributions of such stands,...
