Calculate Y Hat in Excel
Understanding Y Hat in Linear Regression
Y hat represents the predicted y value in a linear regression equation. Calculate it using the formula y-hat = b0 + b1*x, where b0 is the y-intercept and b1 is the slope of the trendline.
Excel Functions for Y Hat Calculation
Excel's SLOPE and INTERCEPT functions are essential for finding y hat. The SLOPE function returns the slope (b1), and the INTERCEPT function provides the y-intercept (b0) of the linear regression line.
Steps to Calculate Y Hat
To predict y hat in Excel, first use the SLOPE function to find b1, then use the INTERCEPT function to determine b0. Combine these constants in the formula y-hat = b0 + b1*x to calculate y hat for any x value.
Using Excel's Tools for Linear Regression
Perform linear regression in Excel using the Regression ToolPak, scatter chart with trendline, or linear regression formulas. Each method may yield slightly different results due to computation variations.
