Abstract

Up to 24 Feb 2012 Swift has triggered on 638 GRBs. In this work we use the pattern of the missing gamma, X-ray and optical data measured by BAT, XRT, UVOT and ground based measurements of the redshift, collected for the Swift GRBs ([1]). Using the Boolean factor analysis of multivariate statistical methods we studied the missing data patterns of the gamma, X-ray and optical observed quantities of GRBs. We found that the measured gamma properties have some impact on the missing data in the X-ray and optical domains. The missing data pattern depends, however, on random effects as well.
