Linear Regression Equation
Linear Regression Equation - The formula for a simple linear regression is y is the predicted value of the dependent variable y for any given value of the independent variable x B 0 is the intercept the predicted value of y when the x is 0 Think back to algebra and the equation for a line y mx b In the equation for a line Y the vertical value M slope rise run X the horizontal value B the value of Y when X 0 i e y intercept So if the slope is 3 then as X increases by 1 Y increases by 1 X 3 3 Write a linear equation to describe the given model Step 1 Find the slope This line goes through 0 40 and 10 35 so the slope is 35 40 10 0 1 2

If you suspect a linear relationship between x and y then r can measure how strong the linear relationship is What the VALUE of r tells us The value of r is always between 1 and 1 1 r 1 The size of the correlation r indicates the strength of the linear relationship between x and y
In the linear regression formula the slope is the a in the equation y b ax They are basically the same thing So if you re asked to find linear regression slope all you need to do is find b in the same way that you would find m

In statistics linear regression is a statistical model which estimates the linear relationship between a scalar response and one or more explanatory variables also known as dependent and independent variables
The equation developed is of the form y mx b where m is the slope of the regression line or the regression coefficient and b is where the line intersects the y axis The equation for the regression line can be found using the least squares method where m n xy x y n x2 x 2 and b y m x n
