How do you calculate Studentized residuals in Excel?

How to Calculate Standardized Residuals in Excel

1. A residual is the difference between an observed value and a predicted value in a regression model.
2. It is calculated as:
3. Residual = Observed value – Predicted value.

What should residual plots look like?

The residual plot shows a fairly random pattern – the first residual is positive, the next two are negative, the fourth is positive, and the last residual is negative. This random pattern indicates that a linear model provides a decent fit to the data. Below, the residual plots show three typical patterns.

How do you calculate residuals?

To find a residual you must take the predicted value and subtract it from the measured value.
