Method ao/getdof


  GETDOF Calculates degrees of freedom for psd, lpsd, cohere and lcohere
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
 
  DESCRIPTION: GETDOF Input psd or mscohere (magnitude square coherence)
  estimated with the WOSA (Welch's Overlapped Segment Averaging Method) and
  return degrees of freedom of the estimator.
 
  CALL:         dof = getdof(a,pl)
 
  INPUTS:
                a  -  input analysis objects containing power spectral
                      densities or magnitude squared coherence.
                pl  - input parameter list
 
  OUTPUTS:
                dof - cdata AO with degrees of freedom for the
                      corresponding estimator. If the estimators are lpsd
                      or lcohere then dof number of elements is the same of
                      the spectral estimator
 
 
               If the last input argument is a parameter list (plist).
               The following parameters are recognised.

Key Default Value Options Description
METHOD 'psd'
  • 'psd'
  • 'lpsd'
  • 'mscohere'
  • 'mslcohere'
Set the desired method. Supported values are
  • 'psd' power spectrum calculated with ao/psd, whatever the scale
  • 'lpsd' power spectrum calculated with ao/lpsd, whatever the scale
  • 'mscohere' magnitude square coherence spectrum calculated with ao/cohere
  • 'mslcohere' magnitude square coherence spectrum calculated with ao/lcohere
DATALENGTH [] none Data length of the time series.It is better to input for more stable calculation.Leave it empty if you do not know its value.
CONF 95 none Required percentage confidence level.
It is a number between 0 and 100.
DOF [] none Degrees of freedom of the estimator. If it is
left empty they are calculated.
