What is a fitting parameter?

Parametric fitting involves finding coefficients (parameters) for one or more models that you fit to data. The data is assumed to be statistical in nature and is divided into two components: data = deterministic component + random component.

What are fitted parameter values?

A fitted value is a statistical model's prediction of the mean response value when you input the values of the predictors, factor levels, or components into the model. Suppose you have the following regression equation: y = 3X + 5. If you enter a value of 5 for the predictor, the fitted value is 20.

How do you find the error of the line of best fit?

Error/Residuals

Error is the difference between the actual value of y and the predicted value of y. square the error/residuals. Then we have to calculate the sum of squares of all the errors. Out of all possible lines, the line which has the least sum of squares of errors is the line of best fit.
