Hi everyone, I use statsforecast for my time series project that is based for demand forecasting. So, i have a question for you. I am trying to predict next 13 periods. In some series, model gave me good results when compare with test values. However, in some series, i encounter a problem. The problem is to predict same values in every 13 periods. Is there any reason for this? And can i fix this problem via using model parameters etc.? Thank you for interest.

No. For example, i get 100 for first week, and then i get also 100 for second week, and for all 13 weeks etc.

model wasn't able to capture any significant patterns/variations in your training dataset.

Oh, i get it now. I did some research. I also encounter this.
Actually i use many models and get many predictions. However, i select the best model when comparing validation set. I can give a model for an example. (DynamicOptimizedTheta)
