hwwntest

Provides methods to test whether time series is consistent with white noise. Two new tests based on Haar wavelets and general wavelets described by Nason and Savchev (2014) doi:10.1002/sta4.69 are provided and, for comparison purposes this package also implements the B test of Bartlett (1967) doi:10.2307/2333850. Functionality is provided to compute an approximation to the theoretical power of the general wavelet test in the case of general ARMA alternatives.
