Although the CDF plot reveals the approximate center and scale of the data, I would find it difficult to conclude from the comparative CDF plot that the Gamma variable is skewed whereas the Normal variable is symmetric. Consider rotating the CDF panel 90 degrees in the counter-clockwise direction. If you also center the data so that each variable has zero mean, then the result called a spread plot.

The spread plot, as its name implies, is used to compare the spread range of distributions, as well as to give some indication of the tail behavior long tails, outliers, and so forth in the data. I have previously blogged about how to compute empirical quantiles. In Chambers et al. In Cleveland it is called the f-value, which is short for fractional value. In some SAS output it is labeled "proportion less [than the value shown]. Chambers and Cleveland each use the simpler fractional rank given by ri—0.

I have used Blom's formula, which is used heavily in SAS software. The nice thing about the spread plot is that the range of the data is evident. The range for the centered Gamma variable is [-3,8]. Furthermore, notice that the mean value is greater than the median value, which is a standard rule of thumb for continuous skewed distributions. In contrast, the Normal and Uniform variables are both visually symmetric.

The Normal variable clearly has two moderate tails, whereas the Uniform variable appears to be a bounded distribution. A plot that uses quantiles to compare distributions is more powerful than the technique of comparing histograms. On the other hand if either proportion were close to zero or one, a much larger N would be needed. But, if I were run the same proportions unweighted, should the chi square test be employed? Wrong question. Using the sampling weights it not optional when the data come from a non-simple random sample.

Any analysis that ignores the weights is just wrong. I am still under the impression from what I have read that chi square and proportions is used when you are comparing proportions a generated into two separate samples or b with the same sample but at two different times.
