題目如下: Let U be a uniform random variable on interval(0,1). Suppose that the conditional distribution of X, given U = p, is binomial with parameter(n,p). Find the probability mass function of X. 感謝回答! :] -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.112.244.81

U~U(0,1) , X|U=p~Bin(n,p) 求f(x)

f(x,p)=f(p)f(x|p) , f(x)=∫f(x,p)dp
