Semiparametric Stepwise Regression to Estimate Sales Promotion Effects (2008)
Winfried J. Steiner, Christiane Belitz, Stefan Lang
semiparametric models to estimate the influence of price promotions on brand sales, and both obtained superior performance for their models compared to strictly parametric modeling. Following these...
Model Selection in Generalised Structured Additive Regression Models (2007)
In recent years data sets have become increasingly more complex requiring more flexible instruments for their analysis. Such a flexible instrument is regression analysis based on a structured...
