"The Bulgarian TV show Otechestven Front – which translates loosely as The Home Front – does seem to be experiencing a cluster of bad luck," he writes.
Lacking the equanimity to deal with clusters of bad luck and "cold," unplayable cards, he fell into a vicious cycle of increased losses and erratic play.
Instead, the nation's biggest cluster of bad sleep ended up in the heart of Appalachia and in a cluster of counties in Ohio, West Virginia, Kentucky, Virginia and Tennessee.
Often, there are clusters of bad pixels, and of course, any indication at the same size and inside such a cluster would be averaged away.
The Illumina clusterplots of the SNPs with P < 1 × 10−4 (n = 71) were visually inspected to confirm high-quality genotyping, and 9 SNPs were excluded on the basis of bad clustering in the LLS GWAS cases or RS GWAS controls.
Indeed, one interesting aspect of the algorithm used here is the separation of the algorithms used for detection of bad clusters, which relies on a logistic classifier, from that used for bad cluster partitioning (which relies on graph-based edge editing), and which was designed for the situation in which identifier error is relatively rare.
Thus, ~96.9% of bad clusters of this type can be successfully resolved by the algorithm described.
Thus, we estimate the classification system detects over 97% of bad clusters, with an approximate 1% false positive rate.
And the same was true of bad behaviors — clusters of friends appeared to "infect" each other with obesity, unhappiness and smoking.
A correspondence analysis of the 3.000 genes with the highest variance showed clear clustering of patients with good or bad prognosis, respectively.
