The Normal QQ plot is used to evaluate how well the distribution of a dataset matches a standard normal (Gaussian) distribution. The general QQ plot is used to compare the distributions of any two datasets.

GQQPLOT(X,'binom',N). The name of the distribution can be (case insensitive): 'norm' or 'normal' 'gam' or 'gamma' 'logn' or 'Lognormal', 'exp' or 'Exponential', 'wbl' or 'Weibull'. 'beta' 'bin' or 'Binomial' 'ev' or 'Extreme Value', 'gev' or 'Generalized Extreme ...
The normal characterization results in some independent spherical distributions. The affine invariance of the SW statistic and a simple property of spherical distributions are employed to construct the QQ plot. Easy simulation of the empirical distribution of the SW statistic avoids the complicated exact...

去年考到了QQ plot,因为错的十分惨烈,到现在都对当时对答案时的场景印象深刻。但是直到半年后的现在才大概明白QQ plot,该打。 简要概述:QQ plot(quantile-quantile plot),也称正态概率图(normal probability plot),是常用的统计分析用图,用于检查一组数据是否服从正态分布,是实数与正态分布数据间的函数关系的散点...
QQ-plots in R, first need to understand the Q-Q plot. The Q-Q plot is a graphical tool to help us examine if a set of data plausibly came from some theoretical distribution such as a Normal or not. Suppose, if we are executing a statistical analysis the test comes under parametric ...
