adjust_lag2_corrcoef2
(gamma_1, gamma_2)¶ A more advanced adjustment of lag-2 temporal autocorrelation coefficient to ensure that the resulting AR(2) process is stationary when the parameters are estimated from the Yule-Walker equations.
Parameters: - gamma_1 : float
Lag-1 temporal autocorrelation coeffient.
- gamma_2 : float
Lag-2 temporal autocorrelation coeffient.
Returns: - out : float
The adjusted lag-2 correlation coefficient.
