statsmodels.tsa.stattools.pacf_yw

statsmodels.tsa.stattools.pacf_yw(x, nlags=40, method='unbiased')

Partial autocorrelation estimated with non-recursive yule_walker.

Parameters

xarray_like

The observations of time series for which pacf is calculated.

nlagsint, optional

The largest lag for which pacf is returned.

method{‘unbiased’, ‘mle’}

The method for the autocovariance calculations in yule walker.

Returns

ndarray

The partial autocorrelations, maxlag+1 elements.
