The general manager of a chain of pharmaceutical stores reported the results of a regression analysis, designed to predict the annual sales for all the stores in the chain (Y) – measured in millions of dollars. One independent variable used to predict annual sales of stores is the size of the store (X) – measured in thousands of square feet. Data for 14 stores were used to fit a linear model. The results of the simple linear regression are provided...

solve part B
Note: Do not use MATLAB (or other programming languages) build-in functions for regression. (a) Write a MATLAB (or other programming languages) function that accepts n values of xi and Yi, perform Linear Regression and returns values of rand, the model parameters ao and a. (6) Write another MATLAB (or other programming languages) function that accepts n values of X, and y(provided as arrays), checks for Linear, Power (y = axBx) and Saturation growth- rate (y = a*)...
