similar courses. A study is conducted to determine a regression model for estimating individual's body fat. Three independent variables (Input variables) are Tricep_skinfold, Thigh_Circum, and Midarm_circum. Use these three inputs and apply stepwise variable selection technique to build a model to predict Bodyfat. Report your best model along with ANOVA table and make a prediction of the body fat for the individual with the three inputs (Tricep_skinfold, Thigh_Circum, and Midarm_circum) = ( 50, 30, 20) and obtain a 95% confidence interval for your prediction. You can use any software to do this.
