Hello everyone, I would like to have an Excel SpreadSheet with a Macro that allows me to select between the following Models (in the form of a combobox): AR, MA, ARMA and ARIMA. And depending on the model chosen, give Excel the parameters (for p, q, d and P, D, Q). I want to find a way to connect R with Excel in such a way that, If I select the desired model and the required parameters I could pass those to the arima.fit function and then generate the graph and produce the forecasts from R. Is there a way to do this?
