Abstract: A statistical analysis has been done by Schmidt (2009) [1] on the GRB prompt emission data of the GUSBAD catalog (Schmidt 2004 [2]), where a collection of sources from the BATSE detector were selected.In this analysis is assumed that GRBs are described by five different Gaussian luminosity functions, which correspond to five spectral classes obtained from the four channels of the BATSE detector.A GRB sample with redshift from Swift is used to calibrate the luminosity function.It is also used the Euclidean value of V /V max as a cosmological distance indicator, since GUSBAD sources do not have measured redshift.A correlation V /V max vs E ob pk , and then L iso vs E pk , is obtained.It is also found the Malmquist bias for GRBs with lower energy,
