WebApr 11, 2024 · Here a one-dimensional Kalman filter was used, which tracks a single state variable, in this case elevation. From the Python package pykalman the Kalman filter was initialized with the initial state of the elevation value of the first photon and then the Kalman smoothing algorithm plus Gaussian smoothing was used. WebThe generalized sign test statistic ( H0: E(CAAR) = 0 ) is given by. zgsign = (w − Nˆp) √Nˆp(1 − ˆp), where w is the number of stocks with positive cumulative abnormal returns during the event period. To compute the p-value, a normal approximation to the binomial distribution with the parameters ˆp and N, is used. molton brown advent calendar 2020
