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".

WebPerforms a nonparametric test for the event study, which is described in Corrado and Zivney 1992. This test is similar to procedure, described in Brown and Warner 1985 (t-ratio), but instead of using abnormal returns, the test uses G i, t = s i g n ( A i, t − m e d i a n ( A i)) . sign and median are ones, which have the same definition as R ... 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. http://irudnyts.github.io/estudy2/reference/car_rank_test.html lofted materials

For instance, Coca-Cola acquired Fairlife on January 3, 2024, and PepsiCo acquired Rockstar Energy Drink on March 11, 2024. Unfortunately, as is, estudy2 does not analyze events that happened on different dates – the event dates have to match. In this short vignette, the workaround is shown.
