请教各位大侠,x1,x2,...,xn服从正态分布,要检验H0:mu=0,sigma=1 <-> H1:not H0,在H0下,对于n=30重复2000次模拟其lrt统计量的分布?这个怎么编程实现呢?
O(∩_∩)O谢谢

[code:1a498wn1]data normal;
call streaminit(13245);
array x[30] x1-x30;
do times = 1 to 2000;
do i = 1 to dim(x);
x[i] = rand('Normal',0,1);
end;
output;
drop i;
end;
run;[/code:1a498wn1]
