The formula for calculating the Y-Hat value is the estimated or predicted value of the dependent variable (Y) in a regression model. It is calculated by multiplying the regression coefficient (β) by the independent variable (X) and adding the intercept (α). The resulting value represents the expected value of Y based on the relationship between X and Y in the regression model. This formula is used to make predictions and evaluate the strength of the relationship between the variables in the model.

In statistics, the term y hat (written as ŷ) refers to the estimated value of a response variable in a linear regression model.
We write an estimated regression equation as follows:
ŷ = b0 + b1x
where:
- b0 = The average value of the response variable when the predictor variable is zero
- b1 = The average change in the response variable associated with a one unit increase in the predictor variable
- x = The value of the predictor variable
To calculate the value of y hat for a given regression model, simply enter the values for the regression model below and then click the alculate” button:
b0
b1
x
ŷ = 30.36000
function calc() {
//get input data
var b0 = +document.getElementById(‘b0’).value;
var b1 = +document.getElementById(‘b1’).value;
var x = +document.getElementById(‘x’).value;
var y = b0 – (-1*b1*x);
//output results
document.getElementById(‘y’).innerHTML = y.toFixed(5);
} //end calc function
