This is an R package for implementing the covariance completion algorithm in [1]. The variable Cov
is a discretization of the partial covariance Omega
is a matrix of 1s and 0s of the same dimensions as Cov
which describes the domain
- For manual choice of truncation parameters used in the function:
Compln(Cov, Omega, VectorOfTuning)
Here VectorOfTuning
is a vector of integers which serve as truncation parameters in the matrix multiplication involved. Naturally, the length of this vector should be at least
- For automatic choice of truncation parameters in accordance with the fraction of variance explained (FVE) criterion:
ComplnFVE(Cov, Omega, FVE)
