一、quantile-quantile plots 的意思是分位数-分位数图/Q-Q图（参考DictALL词都）二、quantile plot 分位数图 例句The thought of quantile plot in data mining was promoted novelly to measure VaR for risk control and invest decision.提出了将数据挖掘中分位数图的思想应用于VaR测量的新方法...
Quantile‐quantile (Q‐Q) plot. No evidence of systematic inflation of p-values was found (λ = 1.007). The plots compare additive model statistics to those expected under the null distribution using fixed‐effects for all analyzed imputed SNPs passing quality control criteria in the studies...
The Q-Q plot, or quantile to quantile plot, is agraph that tests the conformity between the empirical distribution and the given theoretical distribution. One of the methods used to verify the normality of errors of aregression model is to construct aQ-Q plot of the residuals. If the ...

一般我们会在Q-Q图上做一条45度的参考线。如果两组数据来自同一分布,那么样本数据集的点应该都落在参考线附近;反之如果距离越远,这说明这两组数据很可能来自不同的分布。 python中利用scipy.stats.percentileofscore函数可以轻松计算上诉所需的百分位数;而利用numpy.polyfit函数和sklearn.linear_model.LinearRegression...
