标题[问题] 复回归的样本数(n)怎麽求？
时间Fri Dec 14 07:43:59 2007
题目是：
You are given the following regression results:
^
Yt=9734.2-3782.2 X2t+2815 X3t R^2=0.7706
t =(3.3705)(-6.6070)(2.9712)
can you find out the sample size underlying these results?
(Hint:Recall the relationship between R,F and t values)
希望有人教我
万分谢谢
