WebThis function performs a test proposed by Lamb 1995 to investigate whether CAR significantly differs from zero. This tests uses the variance, specified by Lamb 1995. The advantage of this test is allowance for correlated cross-sectional returns. The test statistic is close enough to statistic, produced by car_brown_warner_1985.

WebAn implementation of a most commonly used event study methodology, including both parametric and nonparametric tests. It contains variety aspects of the rate of return … WebThis test performs t-test based on Patell's standardized residuals. By combining Patell's and t-tests, this test allows for event-induced variance changes, but still assumes cross-sectional independence. The test examines the hypothesis whether the theoretical cross-sectional expected value for a given day is equal to zero.

WebThe algorithm is the following: for each day in event window the cross-sectional abnormal returns treated as sample of differences. Firstly the absolute value of these differences are computed, and corresponding ranks of non-zero values are calculated. The test statistic is the sum of ranks, corresponding to positive abnormal returns.
