Control Inverse matrix noise with Extension
Calculates the extented covariance matrix estimation as described in Marroig et al. 2012
ExtendMatrix(cov.matrix, var.cut.off = 1e-04, ret.dim = NULL)
cov.matrix |
Covariance matrix |
var.cut.off |
Cut off for second derivative variance. Ignored if ret.dim is passed. |
ret.dim |
Number of retained eigen values |
Extended covariance matrix and second derivative variance
Covariance matrix being extended should be larger then 10x10

cov.matrix = RandomMatrix(11, 1, 1, 100) ext.matrix = ExtendMatrix(cov.matrix, var.cut.off = 1e-6) ext.matrix = ExtendMatrix(cov.matrix, ret.dim = 6)
