Released: Dec 8, View statistics for this project via Libraries. This repository is a scikit-learn extension for time series cross-validation. It introduces gaps between the training set and the test set, which mitigates the temporal dependence of time series and prevents information leakage.

Raw Blame History. Each training set consists of ' observations before the test set. This is also called "evaluation on a rolling ' forecasting origin". If a number, then it is the minimum allowable ' size of a test set. This allows for a rolling window ' training set, instead of using all obsservations from the start of the time series.

This rows are assumed to be ordered. The groups are assumed to be ordered, and ' the cross validation works on groups rather than rows. You signed in with another tab or window.

It's okay, I've figured it out. Why doesn't it work in the case of an ELM extreme learning machine when there is xreg? Without xreg the tsCV works perfectly. This is a matter for trnnickthe author of nnfor.

You had some errors in the lines outside of elm or tsCV. See correction below: Check lines for X and newX. I am not sure what you want to do with this, but make sure it does what you want it to do! Have a look at the help of elmit does not use xreg like other functions in the forecast package!

Hi I am not sure if this is a bug, but I am trying to implement the code tscv-xreg. R with xreg with more than one column and I am having an error with the tsp inside the tsCV function when checking for xreg. The only thing I believe I am doing different is that my time series are in quarters, bellow my code, I hope you can give me some hints. You have used Y. So sorry for my previews typo and thanks for your support, if I run this code, I get the same error.

When your test it for quarter ts data it fails. Your xreg needs to be of the same length as the training data. Change the end argument to match. Thanks for the support, it worked. Sign up for free to join this conversation on GitHub.
