Hi there, I need help on the following problem. Any suggestions will be much appreciated. Let x be an i.i.d. random sample of a continuous variable. For some fixed numbers a1<a2<a3<...<ak, we don't observe x, but some grouped information: 1) the frequency of x falls in each interval (a1, a2], (a2, a3], (a3, a4],... 2) the conditional mean of x within each interval, mu1, mu2, mu3,... Is there a way to generate a random sample based on the grouped information on frequency and mean of each interval? Thanks for the help. Ximing
