... air quality forecasting is used to predict the change trend in air quality in the future. Air quality forecasting is usually based on historical data and monitoring data, using statistical methods, numerical models, artificial intelligence algorithms, expert experience comprehensive judgment, etc., which can be divided into short-and medium-/long-term predictions.  2, fiche 1, Anglais, - air%20quality%20forecasting

HAPC [hierarchical age-period-cohort] modeling is an epidemiological method capable of decomposing prevalence rate into mutually independent age, period and cohort effects with individual-level data, while the estimated period and cohort effects provide an unbiased measure of historical trend controlling for the effects of age and other covariates.  2, fiche 2, Anglais, - historical%20trend

A modeling process by which variation in a time series are assumed to be explained wholly by the historical trends of the data itself. In essence, the ARIMA modeling process consists of the autoregressive and moving average processes of the Auto-Regressive Moving Average(ARMA) Model process on data that have been Differenced to render them Stationary. The process uses variations of differencing and transformations to describe historical patterns in the data. Like the simpler ARMA model, forecasts made by an ARIMA modeling process consist of only a mathematical process of projecting inherent characteristics of trend, cycles, and seasonality into the future and incorporate no economic relatinships. Consequently, such models are not appropriate for impact analysis or for incorporating random "shocks", but may prove an effective estimation process when the trends in the historical data are relatively stable and well-behaved.  1, fiche 4, Anglais, - auto%2Dregressive%20integrated%20moving%20average%20process
