Bootstrap-basedmodel selection has been shown inmany practical instances to be superior to classical methods such the AIC and MDL. This is particularly noticeable when the distribution of modelling noise is unknown and/or when the available data samples are small. One of the main problems of using bootstrap model selection with real data is the necessity of tuning the residual scaling parameter or estimating the length of a sub-sample. Recently, we have developed a new hook and loop (HL) resampling plane, in which the scaling of the residuals is avoided. Here, we compare the performance of the range of resampling planes that can be used in the context of model selection and show that the HL-based model selection is superior to its predecessors. Moreover, in the context of fitting parametric models to corneal data measured by videokeratoscopes, the HL provides results that are consistent with clinical expectations.
Impact and interest:
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
