【 摘 要 】

In this article we discuss the application of the bootstrap method for the large-scale cosmic rays anisotropy study in the PAMELA experiment with the calorimeter. This method was used to obtain the statistical uncertainties for the dipole phase and amplitude in the case when the collected in the experiment number of events was not sufficient enough for the direct observation of the anisotropy.
