The galaxies observed within the error boxes of gamma-ray bursts are inconsistent with the host galaxies predicted by the simplest "minimal'' cosmological model where bursts emit $\sim 6\ 
10^{50}$ ergs but are consistent with a standard candle energy of $\sim 10^{53}$ ergs (if radiated isotropically). Although these calculations utilize the host galaxy data but not the burst intensities, we have developed the methodology to use all the available observations to model the redshift and intensity distributions.

Key words: gamma-rays: bursts -- methods: statistical
