WebThe strucchange package provides various types of methods. First, structural change tests based on F statistics in linear regression models ( Fstats ), empirical fluctuation processes in linear regression models ( efp ), and generalized empirical fluctuation processes in parametric models ( gefp ) are available in the corresponding sctest methods. WebApr 11, 2015 · Strucchange provides some functionality with respect to calculating heteroskedasticity ( HC) and autocorrelation ( HAC) consistent covariance matrices, e.g., the approaches suggested by Newey-West (1987) or Andrews (1991). However, this functionality in strucchange is limited to the function gefp that calculates Generalized …
