WebIn statistics, Poisson regression is a generalized linear model form of regression analysis used to model count data and contingency tables. Poisson regression assumes the response variable Y has a Poisson distribution, and assumes the logarithm of its expected value can be modeled by a linear combination of unknown parameters. http://sdos.lib.ntnu.edu.tw/search.result.jsp?query_term1=accident+&query_term2=&query_term3=&index_1=jo_name_search&class=keywords&datas=Poisson
