Least squares linear regression is a method for predicting the value of a dependent variable Y, based on the value of an independent variable X. Prerequisites for Regression. Simple linear regression is appropriate when the following conditions are satisfied. The dependent variable Y has a linear relationship to the independent variable X.

Excel (and most scientific calculators) can perform non-linear regression directly on non-linear data. This route is usually easier. LINEAR REGRESSION OF NON-LINEAR DATA (after converting the data): We will consider one example here. A very common example is a multipoint calibration with specific ion electrodes.

Empty your bag of M&M™’s onto the table and count the M&M™’s. Then place the M&M™’s in a cup and mix them well. Pour them out on the desk, count the number that show an “m,” and place them back in the cup. The others may be eaten or removed. Record the number of M&M™’s that show an “m” in your data table.

Think about how much work you have to do to plot these data if you don’t have your lovely calculator. Next, we will do a data regression (fitting the data into a function). Tap menu item Calc. Tap Linear Reg, meaning we will fit the data into a linear function. Change “Copy Formula” to y1. This will save your regression function to y1.

Your calculator can find the equation of the line of best fit through a process called linear regression. This is a statistical calculation, so the command is found in the STAT CALC menu 4:LinReg(ax+b). Note that the calculator uses a for the slope and b for the y-intercept. Hit ENTER to bring the command to the home screen and ENTER again to ...
