Abstract
Regression analysis of the newest ISHPDB database version agrees well with the ISS04 scaling. The performed cluster analysis shows the existence of significant cohesive subgroups of data and thereby a necessity for grouping data in the scaling procedures. The gathered experiences can be useful for further ISHPDB studies (not only scalings), the more so as ISHPDB has not been prepared using a statistically designed experiment, but combined solely according to physical considerations. Further database analyses should also involve collinearity checks and data mining techniques.
