How to use Cullen and Frey graphs for downstream statistical analysis?

I do not see any difference in normalized and raw data Cullen and Frey plots!

Raw data

summary statistics
------
min:  15.79852   max:  23.55614 
median:  18.76461 
mean:  18.99634 
estimated sd:  1.157783 
estimated skewness:  0.7445161 
estimated kurtosis:  3.325692

  • "I do not see any difference in normalized and raw data Cullen and Frey plots!" -- Naturally not, since skewness and kurtosis is independent of location and scale. They're the third and fourth moments of standardized variables, so in a plot of kurtosis vs skewness-squared any linear rescaling will give the same plot. You should understand the properties of your tools before trying to use them!. 2. It's not clear to me what you mean by "downstream".

    Normalization can mean various things, but none of those I can recall result in the minimum, median, maximum, skew, kurtosis being slightly different and the mean and SD identical to 7 sig. fig. So what did you do? – Nick Cox Mar 21 '19 at 15:55
