Suppose that we want to find a regression equation relating systolic blood pressure (y) to weight (x1) and age (x2) and exercise status using the following data (note that only the first 4 rows of data are shown): ↓ C2 C5 C6 C8 Age Exercise Weight Systolic 1 36 1 215 163 2 43 1 127 132 3 47 0 132 138 4 48 2 196 148 Since exercise status is categorical, we first create the following three indicator variables,...
In determining the best companies to work for, a number of variables are considered, including size, average annual pay, and turnover rate, etc. Moreover, employee surveys are conducted in order to assess aspects of the organization's culture, such as trust and openness to change. In an attempt to determine what affects turnover rate, a sample of 33 companies was randomly selected and data collected on the average annual bonus and turnover rate (%) for 2015. In addition, a questionnaire was...
