order statistics covariance what is the covariance of the iid statistics? how is covariance of iid statistics determined which order statistics are positively correlated is it known that all order statistics are positively correlated what order is a statistic? what is the covariance of inid order stats what is the iid case ind case definition what is the covariance of the iid if an iid statistic is positive, how is this true? in the iid case, it is known is iid positive or negative what is covariance? what is the iid order statistic covariance of iid order statistics what is the covariance of the inid statistic? what case is the inid case? how does the order statistic in iid compare to other orders which order statistics have a co-variance?
