Computational resources for test proposed by Gibbons, Ross, Shanken (1989)<DOI:10.2307/1913625>. It also has the functions for the power analysis and the choice of the optimal level of significance. The optimal level is determined by minimizing the expected loss from hypothesis testing.

Index: This package was not yet installed at build time.
The package accompanies the working paper:
Kim and Shamsuddin, 2017, Empirical Validity of Asset-pricing Models: Application of Optimal Significance Level and Equal Probability Test
The function GRS.test returns the GRS test statistics with model estimation results.
The function GRS.MLtest provides an alternative test statistic with theta and theta* estimation results.
Additional functions for the power analysis and calculation of optimal level of significance are also included.
