Multiple Linear Regression Analysis of Quantities of Daily 110 Emergency Cases and Weather Factors Based on SPSS

Linear regression analysis is a statistical analysis tool studying connection of a dependent variable and an independent variable, aiming to predict value of the dependent variable on the basis of the given value of an independent variable. If there is more than one independent variable, and a linear relationship exists between the dependent variable and the independent variables in linear regression analysis, it is named as multiple linear regression analysis. In this article, Y indicates daily quantities 110 emergency case, X1 indicates the air temperature, X2 indicates wind power, and X3 indicates wind type (sunny, cloudy, rainy, snowy, etc.). We will analyze the relationship between quantities of daily 110 emergency cases and weather factors by constructing a multiple linear regression model.
