Simplify the "directions" element of the output of fimIdent, by setting all elements smaller than a threshold (in absolute value) to 0. The resulting vectors are scaled to their original norms.

simplifyFimIdent(fimId, tol = 0.001)

Arguments

fimId

Named list of FIM identifiability indicators as produced by fimIdent.

tol

Threshold for setting elements to 0. Default value 0.001, i.e. all elements contributing less than 0.1% to the Euclidean vector norm are set to 0.

Value

The list fimId, with a modified "directions" element. If the input list fimId does not contain this element, then it is returned without change.
