STATISTICAL REPORT 2

Statistical methods

This paper attempts to use multiple regression analysis to create model for the amount of

gifts based on past giving and demographic features of the donors. The data comprises of 26

predictors and 1 response variable. The response variable is (GIFTAMNT) is the amount of

money donated by the donor. The regression method is most appropriate method to use since the

aim of the study is to identify relationships and trends in the data and use those trends to make a

prediction about the response variable. There are one dependent variable and multiple predictor

variables and as such, multiple regression models will be used.

Data-driven decision

The process of finding the appropriate regression model for the data can be achieved as follows;
