如何在MATLAB中计算99％的覆盖率? [英] How to compute 99% coverage in MATLAB?

问题描述

我在MATLAB中有一个矩阵，我需要为每一列找到99％的值.换句话说，该值使得99％的人口具有比其更大的价值. MATLAB中是否有为此功能的功能?

I have a matrix in MATLAB and I need to find the 99% value for each column. In other words, the value such that 99% of the population has a larger value than it. Is there a function in MATLAB for this?

推荐答案

使用QUANTILE函数.

Use QUANTILE function.

Y = quantile(X,P);

其中X是矩阵，P是标量或概率向量.例如，如果P = 0.01，则Y将是每列值的向量，因此99％的列值会更大.

where X is a matrix and P is scalar or vector of probabilities. For example, if P=0.01, the Y will be vector of values for each columns, so that 99% of column values are larger.
