The simple linear model is expressed using the following equation. In regression analysis we can predict or estimate the value of one variable with the help of the value of other variable of the distribution after fitting to an equation. Y the dependent variable of the regression m slope of the regression x1 first independent variable of the regression the x2 second independent variable of the regression the x3 third independent variable of the regression b constant.
Displaystyle frac f bar y s y r xy frac x bar x s x this shows that rxy is the slope of the regression line of the standardized data points and that this line passes through the origin.
The regression equation of y on x is used to predict the value of y with the value of x whereas the regression. Regression analysis simple linear regression. The simple linear model is expressed using the following equation. The equation for this regression is represented by.
