Abstract
Holst [10] introduced a discrete spacings model that is related to the Bose-Einstein distribution and obtained the distribution of the number of vacant positions in an associated circle covering problem. We correct his expression for its probability mass function, obtain the first two moments, and describe their limiting properties. We then examine the properties of the vacancy statistic when the number of covering arcs in the associated circle covering problem is random. We also discuss applications of our results to a study of contagion in networks.

These cases are of interest because the unconditional probability that a bank is bad is higher than, equal to, and lower than the probability that a bank is bad conditional on news that another bank is good when M is degenerate, binomial, and a mixture of binomials, respectively. These distinctions turn out to matter when there is some possibility that news about some banks might be revealed.
