R语言内置函数(Built-in Functions) R中几乎所有的事情都是通过函数完成的。 下表提供了其它常用的统计函数。 R语言中每个数值运算函数都有na.rm选项,以便在计算前删除缺失值。否则,缺少值的存在将导致结果也是缺失值。统计函数的运算的对象可以是向量也可以是dataframe Function Description mean(x, trim=0, na.rm...
The quantile() function is used to get values at the given quantile over requested axis. Syntax: DataFrame.quantile(self, q=0.5, axis=0, numeric_only=True, interpolation='linear') Parameters: Returns:Series or DataFrame If q is an array, a DataFrame will be returned where the index is q...

quantile()是R中的一个统计函数,用于计算一组数据的分数或百分比分位数。它提供了四个参数:n是所需分位数的位置,q是从0到1之间的数值,从左到右取值表示从左侧(左闭)的“较低”分到右侧(右闭)的“较高”分的范围,type是类型,可选的参数是“all”(默认为“all”),“lower”(表示从左到右的较低分位点...
使用scipy包中的zscore,对dataframe数据直接进行zscore标准,好处是标准化后的index/columns还在,而使用sklear的标准化处理后,返回的是数组array。[chatGPT]: import pandas as pd from scipy.stats import zscore # 创建训练数据的示例DataFrame train_data = {'A': [1, 2, 3, 4, 5], ...

“分布(数据集)与参考数据集的距离” Sum-of-squares似乎最简单: quants <- seq(0, 1, length.out = 51)ref <- quantile(tt, quants)sumsq <- sapply(list(gg=gg, ff=ff, ps=ps), function(z) sum( (quantile(z, quants) - ref)^2 ))sumsq# gg ff ps # 76290.859 29150.399 4237.075 因此ps...
