WebJul 14, 2024 · The reduced chi-square is obtained by dividing the residual sum of squares (RSS) by the degrees of freedom (DOF). Although this is the quantity that is minimized in the iteration process, this quantity is typically not a good measure to determine the goodness of fit. For example, if the y data is multiplied by a scaling factor, the reduced chi ... WebThe chi-square distribution is equivalent to the gamma distribution where α = k/2 and β = 2. Chart.
