If we're supposed to  An online LSRL calculator to find the least squares regression line equation, slope and Y-intercept values. Enter the number of data pairs, fill the X and Y data pair co-ordinates, the least squares regression line calculator will show you the result. Linear Regression Calculator. This simple linear regression calculator uses the least squares method to find the line of best fit for a set of paired data, allowing you to estimate the value of a dependent variable (Y) from a given independent variable (X).The line of best fit is described by the equation ŷ = bX + a, where b is the slope of the line and a is the intercept (i.e., the value of Loading Least-Squares Regression Line

This page allows performing weighted linear regressions (weighted linear least squares fittings). For the relation between two variables, it finds the linear function that best fits (giving an importance expressed by the weight to each point) a given set of data points.

1 Aug 2018 You will also learn how to draw a regression graph in Excel. However, some programs, including Excel, do the error term calculation behind the scenes. So, in Excel, you do linear regression using the least squares method and seek coefficients a and b such that: Add-ins for Microsoft Outlook online.
