NonlinearityTests function

Nonlinearity tests

NonlinearityTests(
  HRVData,
  indexNonLinearAnalysis = length(HRVData$NonLinearAnalysis)
)

Arguments

• HRVData: Structure containing the RR time series.
• indexNonLinearAnalysis: Reference to the data structure that will contain the nonlinear analysis

Returns

A HRVData structure containing a NonlinearityTests field storing the results of each of the tests. The NonlinearityTests list is stored under the NonLinearAnalysis structure.

Details

This function runs a set of nonlinearity tests on the RR time series implemented in other R packages including:

• Teraesvirta's neural metwork test for nonlinearity (terasvirta.test).
• White neural metwork test for nonlinearity (white.test).
• Keenan's one-degree test for nonlinearity (Keenan.test).
• Perform the McLeod-Li test for conditional heteroscedascity (ARCH). (McLeod.Li.test).
• Perform the Tsay's test for quadratic nonlinearity in a time series. (Tsay.test).
• Perform the Likelihood ratio test for threshold nonlinearity. (tlrt).
