hspec(x, smooth.method = "splines")

Computes the smoothed Haar spectrum of series **x**. Requires
WaveThresh3 if the "wavelets" smoothing method is used.

Takes:

x |
The time series as a vector of observations. Its length does not have to be a power of two if the "splines" smoothing method is used, but does have to be a power of two if the "wavelets" method is used. |

smooth.method |
Method for smoothing the Haar periodogram. Can be set to "splines" (uses smper.spl) or "wavelets" (uses smper.tilw). |

Returns:

TT |
Length of x. |

S |
The sequence of Haar spectrum coefficients. |
