Measurements of the distance between two holes cut into 50 steel sheets are saved as values of the variable DISTANCE in the following data set: data sheets; input distance @@; label distance='Hole ...

Abstract: When a dataset from a non-negative random variable contains zero or very small observations, the folded-normal distribution (FND) can be an appropriate model for fitting the data. Such data ...

Q-Q plot (Quantile-Quantile) plots are graphs of two quantiles against each other. The purpose of a QQ plot is to find whether two sets of data have same distribution. One very common and standard use ...

it follows that an estimate of CPU is 1.7 / 3 = 0.57, and an estimate of CPL is 1.8 / 3 = 0.6. Thus, except for a factor of three, you can estimate CPU and CPL from the points of intersection between ...

geom_qq_line(mapping = NULL, data = NULL, geom = "path", position = "identity", ..., distribution = stats::qnorm, dparams = list(), line.p = c(0.25, 0.75), fullrange ...

We should add a Q-Q plots to scores. Like ROC curves and Murphy Diagrams in scores, this function will produce the output needed for someone to plot it. This should hopefully be very simple to ...

The discussion centered on the use of quantile-quantile plots to analyze stock return distributions and their deviations from the normal distribution assumption, primarily during volatile market ...
