WebHi Iegor, I am using your package for my event sutdy and it is working great. However, I wanted to ask if there are possibilities to report also more statistical properties such as standard errors ... 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.

WebDec 10, 2024 · When calculating the car_mean in car_parametric_tests, only the mean of the ARs are calculated - there is no cumulative summation. e.g., for the calculation of car_mean in the car_lamb process, in ... 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.
WebThe estduy2 package is an implementation of an event study methodology. The event study is a statistical toolbox that allows examining the impact of certain events on the stock valuation of companies. 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).
