1 ， This program asks you to simulate 1000 observations for an F2,3 distribution, starting with normally distributed variables.

(a) provide a quick outline of the steps in your simulation

(b) provide Stata code to simulate the variables(including Xchi2 variables as an intermediate step)

(c) draw a histogram for your simulated data and discuss its shape

老师也不讲的就叫我们自己去找资料学

在stata里怎么做卡方和F的图啊？

2， simulate 10000 draws for X~N(0,1) and Y~N(0,1)

Draw a histgram for X^2+Y^2 ?
