Solved – Training and test data for Holt Winters Method

I am new to forecasting.

I have weekly data.

I want to forecast using the Holt-Winters method.

Should I make training and test subsets of the data?

How important are the training and test data?

Training and test sets are needed to measure a model's out of sample performance, which is essentially a simulation of how the model would have performed if you used it in the past.
