Jackson's statistic for the exponentiality test.
Jackson(x, norm = FALSE)
A numeric vector of length 1
when x
is a
vector, or with length nrow(x)
when x
is a
matrix.
Numeric vector or matrix. In the second case, rows are considered as samples.
Logical: if TRUE
, the statistic is
normalized by using the asymptotic mean and
standard deviation, respectively 2 and 1.
The value(s) of the statistic are the ratio of two weighted means of the order statistics.
