In this paper,we study an influence of malaria in China.Malaria is epidemic in the tropical and the temperate zones,and moreover Plasmodium falciparum has high mortality.We prospect explanatory variables for estimation of incidence through regression analysis and variable selection methods month by month in 69 areas of Hainan,Yunnan province and Guangxi autonomous region,China.The first frequently used variable is the amount of rainfall in the one month ago,and the second is the average of temperature in the one month ago.Amount of rainfall in the two months ago is also frequently used next to cross terms between amount of rainfall in the one month ago and other explanatory variable.The almost all selected variables are empirically well known but some variables,for example,the amount of incidence in the three months ago,are the variable we do not expect to be selected.
