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 ...
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...

Figure 6 shows a QQplot for two sets of data. The x-axis shows quantiles from Set 1 and the y-axis shows quantiles from Set 2. Sometimes statistician chose Q1(p) to be from a theoretical family of distributions, such as the normal family, to see if parametric modeling is reasonable ...

The normal quantilequantile (QQ) plot of residuals is a popular diagnostic tool for ordinary linear regression with normal errors. However, for some generalized linear regression models, the distribution of deviance residuals may be very far from normality,and therefore the corresponding normal QQ plo...
