compute_expected_distance | R Documentation |
Compute the expectation of several metrics under the Mallows rank model.
compute_expected_distance(
alpha,
n_items,
metric = c("footrule", "spearman", "cayley", "hamming", "kendall", "ulam")
)
alpha |
Non-negative scalar specifying the scale (precision) parameter in the Mallows rank model. |
n_items |
Integer specifying the number of items. |
metric |
Character string specifying the distance measure to use.
Available options are |
A scalar providing the expected value of the metric
under the
Mallows rank model with distance specified by the metric
argument.
