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 ...

G14: Quantile-quantile plot (Q-Q plot) (x-axis: the quantile QS(Pi,); y-axis: the order statistic x(i) ) Given a random sample, we often need to find out whether the data can be regarded as a sample from a population with a given theoretical distribution. To look at the closene...
The Q–Q plot is a scatterplot. Each coordinate pair defining the location of a point consists of a data value and the corresponding estimate for that data value derived from the quantile function of the fitted distribution. Adopting the Tukey plotting position formula (see Table 3.2) as the...
