What are the different forecasting methods and how do they compare?

There are several forecasting methods, including qualitative methods like expert opinion, and quantitative methods like time series analysis and regression. Would you like a detailed comparison?

Yes, please provide a comparison of time series analysis and regression.

Time series analysis focuses on historical data to identify trends and seasonal patterns, while regression analysis examines the relationship between variables. Time series is great for predicting future values based on past data, whereas regression can help understand how different factors influence outcomes.

Which method is more accurate?

Accuracy can vary based on the context and data quality. Time series methods are often more accurate for data with strong temporal patterns, while regression is better when you have multiple influencing factors. It's essential to evaluate both methods based on your specific dataset.

Can you suggest when to use each method?

Use time series analysis when you have historical data with trends or seasonality. Opt for regression when you want to understand relationships between variables or when you have multiple predictors.
