Fixing an infelicity in ‘leaps’

Read Original

This technical article examines an infelicity in the 'leaps' package for R, which performs model selection. The author explains the package's history, its use of old Fortran code for exhaustive search, and how its preprocessing step for exhaustive search unintentionally affects the results of forward and backward selection algorithms, leading to a potential bug or undocumented feature.
