Description Usage Format Source References
This data set gives rxc contingency table of the observed population of 5 evolutionary stages of pre-main sequence stars in four nearby star forming clouds. Clouds are listed in order of increasing age, and stellar evolutionary stages are based on the properties of their infrared-emitting circumstellar disks. Sample sizes in a cell range from 0 to 179 stars. This dataset is useful for analysis involving r x c contingency tables with small samples. Further description and references for the dataset are given in Appendix C.2 of Feigelson & Babu (2012).
