1 year ago - Seasonal plots for sales over month
- time plots, explain drops (earthquake, how to handle the outliers)
- scatter plots, see is there correlation between two features
- autocorrelation, how is timeseries correlated to its lags
- STL decomposition (univariate) , trend, season, reminder. reminder should be white noise, shouldnt be trend, if pattern, there must be some feature which influences our data.
