WebDetails. This function performs a test proposed by Cowan 1992 to investigate the significance of the CAR for a given period. In order to get ranks of corresponding abnormal returns, the procedure uses regular R function rank with parameter ties.method = "average" and na.last = "keep". For this test the estimation period and the event period ... 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.

WebThis test examines the equality of the cross-sectional expected value to zero. The standard deviation, which is used in this test, is simply a cross-sectional standard deviation for a given day in the event window. It calculates statistics even if event window and estimation period are overlapped (intersect). WebDetails. This function performs a test proposed by Brown and Warner 1985 to investigate whether CAR significantly differs from zero. This tests uses the variance, specified by Brown and Warner 1985. The advantage of this test is allowance for correlated cross-sectional returns. However, the test does not use autocorrelation adjustment.
