(* Defaults:
        let _minimum = defaultArg minimum 1
*)
-> int

minimum Double (Optional): Optional. The smallest value the eigenvalue for a component may have for the component to be retained. The default value is 1.

Int32
The number of components to retain based on whether the corresponding eigenvalues are greater than minimum.
