Heteroscedastic Linear Models for Analysing Process Data. Juutilainen I, R., J. In 2003. abstract bibtex In this paper the guidelines for applying heteroscedastic linear models for analysing industrial process data is presented. Heteroscedastic linear models are considered as a good model family for the joint modelling of dispersion and mean. The model selection of heteroscedastic linear model is discussed considering the special features of industrial data. A procedure for dispersion model selection based on the validation deviance related to the gamma model on the squared residuals of the mean model is presented. The model selection procedure is tested using simulated data and also in a real industrial application. The estimation and model selection procedures are relatively simple and can be implemented using standard statistical software.
