Quantile Quantile plots. The quantile-quantile plot is a graphical method for determining whether two samples of data came from the same population or not. A q-q plot is a plot of the quantiles of the first data set against the quantiles of the second data set. By a quantile, we mean the fraction (or percent) of points below the given value.

The QQ plot can also be used to compare two distributions based on a sample from each. ... The PP plot is a QQ plot of these transformed values against a uniform distribution. The PP plot goes through the points ((0, 0)) and ((1, 1)) and so is much less variable in the tails:

Quantile – Quantile plot in R which is also known as QQ plot in R is one of the best way to test how well the data is distributed normally. QQ plot is even better than histogram to test the normality of the data. we will be plotting Q-Q plot with qqnorm() function in R. Q-Q plot in R is explained with example.

The qqPlot function is a modified version of the R functions qqnorm and qqplot. The EnvStats function qqPlot allows the user to specify a number of different distributions in addition to the normal distribution, and to optionally estimate the distribution parameters of …

We can produce a quantile-quantile plot (or QQ plot as they are commonly known), using the qqplot function. To use qqplot, pass it two vectors that contain the samples that you want to compare. When comparing to a theoretical distribution, you can pass a random sample from that distribution. Here's a QQ plot for the simulated t-test data:

qqplot produces a QQ plot of two datasets. In short, R's qqnorm offers the same functionality that scipy.stats.probplot provides with the default setting dist=norm. But the fact that they called it qqnorm and that it's supposed to "produce a normal QQ plot" may easily confuse users. Finally, a word of warning.

Normal quantile plots. Because two-sample QQ plots are comparatively rare, most people assume QQ plots are only used to see if a set of values deviates from their expected ('theoretical') normal values. This type of plot is more correctly termed a normal quantile plot, for example as follows:

The uniform distribution is more fundamental. Is there any test for the uniform distribution? QQ plot can be used, but not formal enough. The problem is real. I have some data, I know it is uniformly distributed. However, I don't know how to formally test my hypothesis. When I came to check wiki, I didn't find any.
