L2metric {ddalpha} | R Documentation |
L^2
Metric for Sets of Functional DataReturns the matrix of L^2
distances between two sets of functional data.
L2metric(A, B)
A |
Functions of the first set, represented by a matrix of their functional values of
size |
B |
Functions of the second set, represented by a matrix of their functional values of
size |
For two sets of functional data of sizes m
and n
represented by matrices of their functional values on the common domain {1,...,d},
this function returns the symmetric matrix of size m*n
whose entry in the
i
-th row and j
-th column is the approximated L^2
distance of the
i
-th function from the first set, and the j
-th function from the second set.
This function is utilized in the computation of the h-mode depth.
A symmetric matrix of the distances of the functions of size m*n
