标 题: find distribution paramters only by data mean and std. dev.
发信站: BBS 未名空间站 (Mon Mar 17 17:14:15 2014, 美东)
I need to estimate a truncated gamma distribution paramters (shape , scale).
But, I only know the data mean and std. dev. I do not know the dat set.
Given the mean and std. dev. of a data set from a trucnated gamma
distribution, how to find shape and scale of the distribution parameters ?
I know MLE may be sueful for solving this problem. But, they depend on
knowing the whole data set.
Any help would be appreciated. |
