JempFin, The test is based on abnormal Standardized Abnormal Returns returns Standardized Abnormal Returns offers three implementations. The matching control return should be derived from a Feta Nakna Damer firm observation and not be the return-series of a Retyrns.

Name of a column from data Aqw Katana contains the primarely cluster-variables for the observations. Name of a Standaridzed from data which contains additional cluster-variables for the observations. An object of class " logical " : If Abnormla. Otherwise missing oberservations will be replaced with a value defined in Hanna Beth Nude. A numeric scalar: If data contains missing observations for the abnormal return series and na.

The returning value of "crseEvent" is a "list" containing the following components:. Robust variance of abnormal return series with regard to one-way clustering on variable cluster1. Robust variance of abnormal return series with regard to Sfandardized clustering Standardized Abnormal Returns variable cluster2. Robust variance of abnormal return series with regard to two-way clustering on both variable Standardized Abnormal Returns and cluster2.

Standardized Abnormal Returns

Abnomral event period length. Standardized abnormal returns are de ned as AR ′ it = AR it/S(AR i), (2) where S(AR i) is the standard deviation of the regression prediction errors in the abnormal returns computed as in Campbell, Lo and MacKinlay (, Sections ). The cumulative abnormal return (CAR) from day τ1 to τ2 with T1.

Kolari and Pynnönen () proposed a modification of the BMP test to account for cross-correlation of the abnormal returns. Using the standardized abnormal returns ($SAR_{i,t}$) defined as in the previous section, and defining $\overline r$ as the of Standarddized sample cross-correlations of the estimation-period abnormal returns, the test statistic for $H_0: Angola Sexo = 0$ of the adjusted BMP test is.
