Optimal Time Plan in Accelerated Degradation Testing
Helmi Shat, Rainer Schwabe
Many highly reliable products are designed to function for years without failure. For such systems accelerated degradation testing may provide significance information about the re…
Experimental Designs for Accelerated Degradation Tests Based on Linear Mixed Effects Models
Helmi Shat, Rainer Schwabe
Accelerated degradation tests are used to provide accurate estimation of lifetime properties of highly reliable products within a relatively short testing time. There data from par…
In- and Equivariance for Optimal Designs in Generalized Linear Models: The Gamma Model
Osama Idais, Rainer Schwabe
We give an overview over the usefulness of the concept of equivariance and invariance in the design of experiments for generalized linear models. In contrast to linear models here…
Optimal Design for Probit Choice Models with Dependent Utilities
Ulrike Graßhoff, Heiko Großmann, Heinz Holling +1
In this paper we derive locally D-optimal designs for discrete choice experiments based on multinomial probit models. These models include several discrete explanatory variables as…
The adaptive Wynn-algorithm in generalized linear models with univariate response
Fritjof Freise, Norbert Gaffke, Rainer Schwabe
For a nonlinear regression model the information matrices of designs depend on the parameter of the model. The adaptive Wynn-algorithm for D-optimal design estimates the parameter…
Analytic solutions for locally optimal designs for gamma models having linear predictor without intercept
Osama Idais, Rainer Schwabe
The gamma model is a generalized linear model for gamma-distributed outcomes. The model is widely applied in psychology, ecology or medicine. In this paper we focus on gamma models…
