Linear Regression Analysis Using Matlab

Data for Lowry protein assay standard curve is given below. The protein solutions are treated with several reagents to yield a blue-colored complex. The intensity of the blue color increases with protein concentration and can be measured as absorbance at 650 nm. Create a USER-FRIENDLY Matlab program that will determine the best fit of the line (y = a + bx) by the use of method of least squares.

Lowry Protein Standard Curve Experimental Data:

-The program should inform the user of what it will do.

-It should display the data table to the user and explain to the user which is the dependent variable and which is the independent variable.

-It should ask the user if it wants to know what linear equation can the given data set best fit into.

--If the answer is yes, the user should be informed what the program will do next until the answer is displayed.

--If the answer is no, the user should be informed that the program wants to be of service by solving the given data set.
