matlab - How to generate the Weibull's parameters k and c in Matlab?

Question

Can anyone explain to me how to generate the Weibull distribution parameters k and c, in Matlab?

I have a file of 8000 data of wind speed, and I'd like to do the following:

1. Generate the Weibull's k and c parameters of those.
2. Plot the probability density function against the wind speed.

I am new in Matlab and have not yet been able to do this.

Answer 1

如果你有统计工具箱，你可以使用fitdist：

pd = fitdist(x,'Weibull')

x你的数据在哪里。我猜它应该返回参数a并b在：

pdf然后，您可以使用该函数计算 pdf（并绘制它） 。的文档中有一些示例（尽管是正态分布）fitdist。
