For example, if you wanted to generate a line of best fit for the association between height and shoe size, allowing you to predict shoe size on the basis of a person's height, then height would be your independent variable and shoe size your dependent variable). Simple tool that calculates a linear regression equation using the least squares method, and allows you to estimate the value of a dependent variable for a.
To begin, you need to add paired data into the two text boxes immediately below (either one value per line or as a comma delimited list), with your independent variable in the X Values box and your dependent variable in the Y Values box. We can write an equation of the line that passes through the points y0 as follows: Using the equation: y 3x 6, put y0. This calculator will determine the values of b and a for a set of data comprising two variables, and estimate the value of Y for any specified value of X. It is the point where the line crosses the x axis of the cartesian coordinates. 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 Y when X = 0). Then it will attempt to solve the equation by using one or more of the following: addition, subtraction, division, taking the square root of each. It takes inputs of two known points, or one known point and the. 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). This slope calculator solves for parameters involving slope and the equation of a line.
