pacf_ols
(x, nlags=40)[source]¶ Calculate partial autocorrelations
Parameters: x : 1d array
observations of time series for which pacf is calculated
nlags : int
Number of lags for which pacf is returned. Lag 0 is not returned.
Returns: pacf : 1d array
partial autocorrelations, maxlag+1 elements
Notes
This solves a separate OLS estimation for each desired lag.
