In repairable system data analysis it is common to many components of the same type are studied and in these cases it is relevant to verify the heterogeneity between systems.
To study the relation between a univariate response and multiple functional covariates,we propose a functional single index model that is semiparametric.
We introduce a method—called Fisher exact scanning(FES)—for testing and identifying variable dependency that generalizes Fishers exact test on 2 × 2 tables to larger tables as well as continuous sampl
