Hi, seems like you were trying to predict
using a within model. That case what not implemented - until now in the development version (commits: b81d759332114e3cafa663fc9217da9f0b8c99e4, 93a51bdf7cdf711d75cf6aa994dd82da9ec25e48, 4c44fef2a5fb0f0c23cae32d549069c66ec4c405, cd48d6fff8a620d596a11527572f559b0fc70ce8) .
Be aware that the within case is somewhat special, more so with out-of-sample prediction. The help page ?predict.plm
has the details and examples.
Feedback is welcome!
To install the development version from GitHub:
# install.packages("remotes") # remove '#' if pkg 'remotes' is not installed
remotes::install_github("ycroissant/plm")

Closing this because it is solved.
On CRAN as plm 2.6-2 as of 2022-08-16
Hi team, thanks for a great package? I check all possible resources, but do not see how to used
predict()
orprediction()
withplm
.Currently I am trying:
predictions <- predict(plmFit1, panel_df_test)
and get
Error in crossprod(beta, t(X)) : non-conformable arguments
