Using a simple uniform jet model of prompt emissions of gamma-ray bursts<br />
(GRBs), we reproduce the observed peak energy--isotropic energy relation. A<br />
Monte Carlo simulation shows that the low-isotropic energy part of the relation<br />
is dominated by events viewed from off-axis directions, and the number of the<br />
off-axis events is about one-third of the on-axis emissions. We also compute<br />
the observed event rates of the GRBs, the X-ray-rich GRBs, and the X-ray<br />
flashes detected by HETE-2, and we find that they are similar.
