dependency_matrix {heuristicsmineR}

Create a dependency matrix

Description

Creates a dependency matrix from a precedence matrix (precedence_matrix) based on different approaches.

Usage

dependency_matrix(
  eventlog = NULL,
  dependency_type = dependency_type_fhm(threshold_dependency = threshold,
    threshold_frequency = threshold_frequency, ...),
  threshold = 0.9,
  threshold_frequency = 0,
  ...
)

Arguments

eventlog

A bupaR event log, may be NULL when a precedence matrix is provided.

dependency_type

Which approach to use for calculation of the dependency matrix. Currently only (dependency_type_fhm) is available.

threshold

A dependency threshold, usually in the interval ⁠[0,1]⁠, filtering out dependencies below the threshold.

threshold_frequency

An absolute frequency threshold filtering dependencies which are observed infrequently.

...

Parameters forwarded to (dependency_type_fhm).

Value

A square matrix with class dependency_matrix containing the computed dependency values between all activities.
