However, GAM assume that the observations are independent, which is generally not the case in time series. In this paper, an autoregressive moving average (ARMA) component is incorporated to the GAM. The resulting GAM-ARMA model is based on the generalized linear autoregressive moving average (GLARMA) model where some linear components are replaced by natural splines. Numerical simulations are presented and show that the ARMA component influences the estimation. In a real data analysis of the effects of air pollution on respiratory disease in the metropolitan area of Belo Horizonte, Brazil, it is shown that the proposed model presents a better fit when compared to the classical GAM approach, that does not take into account the autocorrelation of the data. %G English %2 https://centralesupelec.hal.science/hal-03437160/document %2 https://centralesupelec.hal.science/hal-03437160/file/Generalized%20additive%20model%20for%20count%20time%20series%20An%20application%20to%20quantify%20the%20impact%20of%20air%20pollutants%20on%20human%20health.pdf %L hal-03437160 %U https://centralesupelec.hal.science/hal-03437160 %~ CNRS %~ SUP_LSS %~ SUP_SIGNAUX %~ CENTRALESUPELEC %~ UNIV-PARIS-SACLAY %~ TEST-HALCNRS %~ UNIVERSITE-PARIS-SACLAY %~ GS-ENGINEERING %~ GS-COMPUTER-SCIENCE %~ HUB-IA
