有冇好人識做依條數? [復制鏈接]

1. Suppose x is a continuous random variable having distribution F(x).
(a) Show that y = F(x) is uniformly distributed over (0, 1).
(b) If U is a uniform (0, 1) random variable, then show that F^-1(U) has
distribution F, where F^-1(x) is the value of y such that F(y) = x.

完全唔知想點..

好似係STATISTIC...不過未教

f7 野 未教到

我google到part(a)答案 其實都係轉variable
