Statistically determinate formula
WebThe maximum variance of this distribution is 0.25, which occurs when the true parameter is p = 0.5. In practice, since p is unknown, the maximum variance is often used for sample … WebThe most general definition of the coefficient of determination is R2=1−SSresSStot{\displaystyle R^{2}=1-{SS_{\rm {res}} \over SS_{\rm {tot}}}} In the best case, the modeled values exactly match the observed values, which results in SSres=0{\displaystyle SS_{\text{res}}=0}and R2=1{\displaystyle R^{2}=1}.

WebThere are three simple ways to check for independence: Is P (A) × P (B) = P (A and B)? Is P (B A) = P (B)? Is P (A B) = P (A)? If you answer yes to any one of these three questions then events A and B are independent. Also, if any one of these three is true the others are also true; so you just need to verify that one of them is true.
