Curve Karcher Covariance
Description
Calculate Karcher Covariance of a set of curves
Usage
curve_karcher_cov(v, len = NA)
Arguments
v
array (n,T,N) for N number of shooting vectors
len
lengths of curves (default=NA)
Value
K covariance matrix

Examples
out <- curve_karcher_mean(beta[, , 1, 1:2], maxit = 2)
# note: use more shapes, small for speed
K <- curve_karcher_cov(out$v)
