Research on Population Mortality Based on Generalized Partially Function Linear Model with Interaction Term

This paper briefly introduces a generalized partially function type linear model with interaction terms and applies the model to the study of population mortality, exploring the effects of air quality index, temperature, GDP per capita and number of beds per 1,000 population in hospitals on mortality in selected Chinese cities in 2019. It was concluded that both the air quality index and temperature were positively correlated with the population mortality rate, while GDP per capita and number of beds per 1,000 population in hospitals were negatively correlated with the population mortality rate.
