TheLINESTfunction in Excel is a mathematical tool used to calculate the least squares regression line for a given set of data points. When you apply this function, it returns an array of values, including the slope, y-intercept, correlation coefficient, and regression statistics for the best-fi...

Partial Least Squares regression (PLS) is often used when there are a lot of explanatory variables, possibly correlated. Available in Excel with XLSTAT.
Instead, ordinary least squares regression takes those residuals and squares them, so they’re always positive. In this manner, the process can add them up without canceling each other. Statisticians refer to squared residuals as squared errors and their total as the sum of squared errors (SSE)...
We describe an intuitive and rapid procedure for analyzing experimental data by nonlinear least-squares fitting (NLSF) in the most widely used spreadsheet program. Experimental data in x/y form and data calculated from a regression equation are inputted and plotted in a Microsoft Excel worksheet, ...
