How to find least squares regression line on ti 84
A regression line, or a line of best fit, can be drawn on a scatter plot and used to predict outcomes for the \(x\) and \(y\) variables in a given data set or sample data. There are several ways to find a regression line, but usually the least-squares regression line is used because it creates a uniform line.The formula for the line of the best fit with least squares estimation is then: y = a · x + b. As you can see, the least square regression line equation is no different from linear dependency's standard expression. The magic lies in the way of working out the parameters a and b. 💡 If you want to find the x-intercept, give our slope ...
