In fdasrvf: Elastic Functional Data Analysis

Sample shapes from model

Description

Sample shapes from model

Usage

sample_shapes(mu, K, mode = "O", no = 3, numSamp = 10)

Arguments

mu	array (n,T) of mean srvf
K	array (2T,2T) covariance matrix
mode	Open ("O") or Closed ("C") curves
no	number of principal components
numSamp	number of samples

Value

samples list of sample curves

Examples

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