SumSquaredErrors Command
From GeoGebra Manual
- SumSquaredErrors( <List of Points>, <Function> )
- Calculates the sum of squared errors, SSE, between the y-values of the points in the list and the function values of the x-values in the list.
- Example: If we have a list of points
L={(1, 2), (3, 5),(2, 2), (5, 2), (5, 5)}and have calculated for example:f(x)=FitPoly(L,1)andg(x)=FitPoly(L,2).SumSquaredErrors(L,f)yields 9 andSumSquaredErrors(L,g)yields 6.99, and therefore we can see, that g(x) offers the best fit, in the sense of the least sum of squared errors (Gauss).
