• To draw a Ƶ2 cumulative distribution graph DrawDistChi , , Degree of freedom Data upper limit Data lower limit ∫p = Upper 1 Lower Γ df 2 × 1 2 df 2 ×x df 2 - 1 × - e x 2 dx • Executing DrawDistChi performs the above calculation in accordance with the specified conditions and draws the graph. At this time the Lower < x < Upper region on the graph is filled in. • At the same time, calculation result is assigned to variables p and Ans. • To draw an F cumulative distribution graph DrawDistF , , , Degrees of freedom of denominator Degrees of freedom of numerator Data upper limit Data lower limit ∫p = Upper Γ ndf + ddf 2 Lower Γ ndf 2 × Γ ddf 2 × ndf ndf 2 × x ndf - 1 2 × 1 + ndf × x - ndf + ddf 2 dx ddf ddf • Executing DrawDistF performs the above calculation in accordance with the specified conditions and draws the graph. At this time the Lower < x < Upper region on the graph is filled in. • At the same time, calculation result p is assigned to variables p and Ans. 8-39
