Check If Two Vectors Are Comonotonic
Description
This functions determines if two vectors have a common ordering permutation.
Usage
check_comonotonicity(x, y, incompatible_lengths = NA)
Arguments
x |
numeric vector |
y |
numeric vector |
incompatible_lengths |
single logical value,
value to return iff lengths of |
Details
Two vectors x
, y
of equal length are comonotonic,
if and only if there exists a permutation
such that
and
.
Thus,
orders
x
and y
simultaneously.
Equivalently, x
and y
are comonotonic,
iff for every
i,j
.
If there are missing values in x
or y
, the function
returns NA
.
Currently, the implemented algorithm has time complexity.
Value
Returns a single logical value.
