Method ao/confint


  CONFINT Calculates confidence levels and variance for psd, lpsd, cohere, lcohere and curvefit parameters
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
 
  DESCRIPTION: CONFINT Input psd, mscohere (magnitude square coherence) 
  and return confidence levels and variance for them.
  Spectra are assumed to be calculated with the WOSA method (Welch's
  Overlapped Segment Averaging Method)
 
  CALL:         out = confint(a,pl)
                
 
  INPUTS:
                a  -  input analysis objects containing power spectral
                      densities or magintude squared coherence.
                pl  - input parameter list
 
  OUTPUTS:         
                out - a collection object containing:
                  lcl - lower confidence level
                  ucl - upper confidence level
                  var - expected spectrum variance
 
 
               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.
