标题: 求助，关于weibull参数的求法
请教各位前辈，如果知道X（自变量）和 Y （变量）的值，假设他们满足weibull 分布，怎么用SAS求出two-parameter weibull的参数值呢？
如果别的方法能求也可以。。。小弟是初学，问题可能很弱，麻烦大家了

谢谢大家了。。。。

my level is low too, but what is y? Weibull seems to be a univariate distribution. If y=Prob(X<=x), then the two parameters can be determined if you know two distinct pairs of (x,y), and it's easier to do by hand than with any software.
