How do I choose the right time series model for my data?
Choosing a time series model depends on the characteristics of your data. What type of data are you working with?
I have monthly sales data that shows some seasonality.
For seasonal data, you might consider models like SARIMA or Holt-Winters. Have you tried any specific models yet?
I haven't tried any yet. What factors should I consider when selecting a model?
You should consider the trend, seasonality, and any cyclic patterns in your data. Also, think about the model's complexity and interpretability.
That makes sense! How do I evaluate the performance of the model I choose?
You can evaluate model performance using metrics like AIC, BIC, RMSE, or by checking residuals. Would you like to know more about these metrics?
