如何在Matlab中生成Weibull参数k和c? [英] How to generate the Weibull's parameters k and c in Matlab?

问题描述

有人可以向我解释如何在Matlab中生成Weibull分布参数k和c吗?

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

我有一个8000风速数据文件，我想执行以下操作:

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

1. 生成这些参数的Weibull的k和c参数.
2. 根据风速绘制概率密度函数.

我是Matlab的新手，尚未能够做到这一点.

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

推荐答案

如果拥有统计信息工具箱，则可以使用

If you have the Statistics toolbox, you can use fitdist:

pd = fitdist(x,'Weibull')

其中x是您的数据.我猜它应该在以下位置返回参数a和b:

where x is your data. I'm guessing it should return the parameters a and b in:

然后您可以使用 pdf 功能.在fitdist的文档中有一些示例(尽管是正态分布).

You can then calculate the pdf (and plot it) using the pdf function. There are some examples (albeit for a normal distribution) in the documentation for fitdist.
