  # The least squares regression line calculator

Least Squares Calculator. Least Squares Regression is a way of finding a straight line that best fits the data, called the Line of Best Fit. Enter your data as (x, y) pairs, and find the equation of  ## Calculating a Least Squares Regression Line: Equation

The least squares regression line formula is given as follows: ŷ=bX+a First, we have to accumulate the value for a and b: b = SP/SSx = 9.4 / 13.2 = 0.71212 The values of a is

2)its gives solution in 2 different ways when necessary, 99/year one, and look forward to continue to use this app, and the best part it can even be a shoe you how to solve it, aside from providing me with answers it is intuitive and has an easy to follow step by step guide.

And this is a LIFE SAVER. Being able to just take a picture of the problem and then being able to see all the steps is so convenient and helpful, but the problem is you just need to buy a premium or to log in there app just to know the "solution" of how did they get the answer :(.

## Quick 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

## Least Squares Regression Line

Step 1: For each (x,y) point calculate x 2 and xy. Step 2: Sum all x, y, x 2 and xy, which gives us Σx, Σy, Σx 2 and Σxy (Σ means sum up) Step 3: Calculate Slope m: m = N Σ(xy) − Σx Σy N Σ(x 2) − (Σx) 2 (N is the number of points.) Step 4:
