This function removes ARIMA terms — arima(), ar(),
ma(), and arma() — from a formula so they can be processed on
their own.
Usage
remove_arima_terms(formula)
Arguments
- formula
A model formula that may use standard fixed
effects, random effects using lme4 syntax (see re()), and
random walks defined using the rw() helper function. See the Details
section below for a comprehensive explanation of the supported syntax.
Value
A formula object with the ARIMA terms removed.
