WebMar 23, 2024 · Step 4 — Parameter Selection for the ARIMA Time Series Model. When looking to fit time series data with a seasonal ARIMA model, our first goal is to find the values of ARIMA (p,d,q) (P,D,Q)s that optimize a metric of interest. There are many guidelines and best practices to achieve this goal, yet the correct parametrization of … WebJul 20, 2024 · Since the data is showing an annual seasonality, we would perform the differencing at a lag 12, i.e yearly. ts_s_adj = ts_t_adj - ts_t_adj.shift(12) ts_s_adj = ts_s_adj.dropna() ts_s_adj.plot() Quick Hack – use the following python functions in the pmdarima package to identify the differencing order for trend and seasonality.
