What are some common errors in time series analysis?
Common errors include ignoring seasonality, not checking for stationarity, and failing to account for outliers.
Can you explain why stationarity is important?
Stationarity is crucial because many time series models assume that statistical properties like mean and variance are constant over time.
What are some methods to check for stationarity?
You can use the Augmented Dickey-Fuller test, KPSS test, or visually inspect plots like ACF and PACF.
How can I handle outliers in my time series data?
Outliers can be handled by using techniques like transformation, imputation, or robust statistical methods.
