Abstract:
These programs calculate the VARHAC covariance matrix estimator proposed in Den Haan and Levin (1994) . The GAUSS procedure calculates the VARHAC spectral estimator of the spectral density at frequency zero for a number of input series. Included files: vhgauss3.src, gauss VARHAC procedure. ls.pro, program to calculate OLS parameter estimates and VARHAC standard errors. exam1.dat, sample data file for ls.pro. exam2.dat, a second sample data file for ls.pro. exgauss1.pro, another example program.
