Q-Q图(Quantile-Quantile Plot) 一种用于比较两个概率分布的图形方法。在数据分析中,它通常用来检验数据是否符合某个理论分布(最常见的是正态分布)。 1.图形结构: (1)X轴表示理论分布(通常是正态分布)的分位数。 (2)Y轴表示实际数据的分位数。 (3)图中的点代表这两组分位数...

Quantile plot G1 (x-axis: the cumulative order probability Pi, y-axis: the order statistic xI) for samples with (a) norm, symmetric (Gaussian, normal), and (b) log, asymmetric (log.-normal) distributions, (quantile functions for the normal distribution : classical - solid line, robust ...
qq_plot(y) displays a quantile-quantile plot of the sample quantiles of y versus theoretical quantiles from a normal distribution. If the distribution of y is normal, the plot will be close to linear. qq_plot(x,y) displays a quantile-quantile plot of two samples. If the samples come ...

Aquantile-quantile plot(also called aq-q plot) visually assesses whether sample data comes from a specified distribution. Alternatively, a q-q plot assesses whether two sets of sample data come from the same distribution. A q-q plot orders the sample data values from smallest to largest, then...

Graph.Kit (February 1986) included commands quantile, qqplot and qnorm. Thanks to Pat Branton of StataCorp for this history. 7 Related plots use the same information Cumulative distribution plots show cumulative probability on the y axis. Survival function plots show the complementary probability. ...
