Too many. See [ | Too many to list. See [[Wikipedia:F-distribution]]. | ||
Most important are Chi-sq and T distribution: | |||
* If <math>X \sim \chi^2_{d1}</math> and <math>Y \sim \chi^2_{d2}</math> then <math>\frac{X/d1}{Y/d2} \sim F(d1,d2)</math> | * If <math>X \sim \chi^2_{d1}</math> and <math>Y \sim \chi^2_{d2}</math> then <math>\frac{X/d1}{Y/d2} \sim F(d1,d2)</math> | ||
* If <math>X \sim t_{(n)}</math> then <math>X^2 \sim F(1, n)</math> and <math>X^{-2} \sim F(n, 1)</math> | * If <math>X \sim t_{(n)}</math> then <math>X^2 \sim F(1, n)</math> and <math>X^{-2} \sim F(n, 1)</math> | ||
