i am trying to use python
but i do not understand their example.Suppose
i have this dataset:
values = [2,4,5,6,8,10,12,15,17,18,18,20,21,25,27,30,32]
where this is ordered and yearly.
the first observation starts at 1905
ex: 1905:3,1906:4,1907:5,etc.....
i want to do a time series anysis to forcast.
however, i want to check the performance of my model using the rmse metric and use sklearn TimsSsriesSplit() to measure the perforamce.
i would like the code for this simple example how to do so using 5 splits and outputing the performance.
your welcome to fit any time series model
