it would appear that the latest Gretl version post estimation in both Arima and OLS Analysis Forecast no longer provides the shaded area confidence interval option that was hitherto available. It is a much preferable option to the confidence interval bars which is the only mrthod and clutters up the graphical presentation which aesthetically clutters up the graphical presentation. Indeed the Arima forecast graphic provides the erro bar in the key, but doesn't even plot it. Any chance of restoring the previous choice selection and functionality?

Dear all,

this message is to inform the community about the activity in our
function package repository: during the month of December 2024, 3
packages were updated to a new version:

"graphlasso", by Sven Schreiber (graphical Lasso --- l1 shrinkage for
covariance matrices)
"lomackinlay", by Allin Cottrell and Sven Schreiber (Lo-MacKinlay
variance ratio test for determining if a time series is a random walk
process)
"BACE", by Marcin Błażejowski and Jacek Kwiatkowski (Bayesian Averaging
of Classical Estimates)

I'll reserve a special mention for the "graphlasso", which now uses a
new internal function to speed up computation.

Sorry if this message comes relatively late in the month, but I was away ;)

Download and enjoy!
