Enter the slope, intercept, and X value into the calculator to determine the predicted Y value based on the regression equation. This calculator helps in forecasting and analyzing data trends.

Regression Output Formula

The following formula is used to calculate the predicted Y value based on the regression equation.

Y = β1 * X + β0

Variables:

  • Y is the predicted Y value based on the regression equation
  • β1 is the slope of the regression line
  • β0 is the intercept of the regression line
  • X is the independent variable value

To calculate the predicted Y value, multiply the slope (β1) by the X value and then add the intercept (β0).

What is Regression Analysis?

Regression analysis is a statistical method used for estimating the relationships among variables. It allows for the prediction of a dependent variable based on the value(s) of one or more independent variables. The simplest form of regression, linear regression, uses a straight line to model the relationship between the variables.

How to Calculate Regression Output?

The following steps outline how to calculate the predicted Y value using the regression equation.


  1. First, determine the slope of the regression line (β1).
  2. Next, determine the intercept of the regression line (β0).
  3. Then, input the X value for which you want to predict the Y value.
  4. Use the regression output formula: Y = β1 * X + β0.
  5. Finally, calculate the predicted Y value.
  6. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

Slope (β1) = 2.5

Intercept (β0) = 0.5

X Value = 10

Insert the values into the formula to calculate the predicted Y value.
