In Carribbean ecosystems, parrotfish prey on certain coral species. This work is a statistical analysis of the patterns of parrotfish predation and the corresponding healing patterns of the coral colonies.
When information is continuous, but you only observe binary data, it can be difficult to detect association between variables. This method proposes a new model based on thresholding, and implements a search procedure that identifies groups of latently associated variables.
This method was developed to identify sets of genes that are more inter-correlated under one condition than under another; genes that are correlated among patients with a certain disease, but uncorrelated among those without the disease. The DCM method relies on statistical testing principles to iteratively search until a significantly differential set is discovered.
Judges and justices of the Canadian higher courts typically employ clerks to aid in their opinion writing. This work studies whether statistical methods can identify which justices relied more heavily on their clerks. A related work attempted to identify clerk-authored papers from among the work of a single judge.
