Calculate regression line in excel
How do you calculate a regression line?
A linear regression line has an equation of the form Y = a + bX, where X is the explanatory variable and Y is the dependent variable. The slope of the line is b, and a is the intercept (the value of y when x = 0).
What is the formula for calculating regression?
Use the formula Y = b0 + b1X1 + b1 + b2X2 +...+ bpXp where: Y stands for the predictive value or dependent variable. The variables (X1), (X2) and so on through (Xp) represent the predictive values, or independent variables, causing a change in Y. ... The variable (b0) represents the Y-value when all the independent variables (X1 through Xp) are equal to zero. More items...

What is the formula for regression analysis in Excel?
Generally, multiple regression analysis assumes that there is a linear relationship between dependent variable (y) and independent variables (x1, x2, x3 … xn). And this kind of linear relationship can be described using following formula: Y = constant + β1*x1 + β2*x2+…+ βn*xn.
