WebAbstract: grsftest calculates the Gibbons, Ross, Shanken (Econometrica, 1989) F-test statistic for the test assets and the factor portfolios. grsftest does not adjust for the degrees of freedom, when calculating estimator of the sample covariance matrix of the factor portfolios. This approach avoids a common misrepresentation of the GRS paper. WebThe GRS test assumes returns are homoscedastic with no auto-correlation. For a robust test, using GMM is recommended (see Cochrane's Asset Pricing p230-235). This can be easily implemented using the gmm package. The package's vignette (section 3.5) provides an example for testing the CAPM using time-series regression.
