X Threshold Difference PWIT vs. Quantreg #6

Closed passeroe closed 6 years ago

passeroe commented 6 years ago

The piecewise iterative (PWIT) and quantreg (QR) functions both use ghi as the maximum x-value that can be a breakpoint. The structure of both our internal and external elf method routine allows users to input only one value for ghi. Therefore, the PWIT function can only look for breakpoints lower than what is used in QR. Should we include the option to set different values for ghi for PWIT and QR? Does the PWIT function have the appropriate amount of flexibility that we were aiming for if we keep ghi the same?
