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 ...

In statistics, a Q-Q plot("Q" stands for quantile) is a probability plot, which is a graphical method for comparing two probability distributions by plotting their quantiles against each other.具体做法是 假设有1000个标记，那预测的值就是1/1000,2/1000,3/1000一直到1.而实际测的...

qq_plot(x,y) displays a quantile-quantile plot of two samples. If the samples come from the same distribution,the plot will be linear. The inputs x and y should be numeric and have an equal number of elements; every element is treated as a member of the sample. ...
