Hello, I'm trying to build a for loop, where I estimate a series of models with different sets of (time series) data. However my for loop doesn't recognize the i # code window.1=anomalies.CAK[(positions(anomalies.CAK)=timeDate(1/1/1971)

[R] Including exogenous X-variables in ARFIMA models

Does anybody know if there is a way to include exogenous X-variables in an ARFIMA model? It appears the ARFIMA function in fracdiff does not support this. Supposing there is nothing already written, and I wanted to modify the existing arfima function, how would I go about this? Would I need to
