The three new parameters of cosmic gamma-ray bursts are introduced: the emission time, the peak energy of the emission time spectrum and the cosmological invariant parameter. ... Using this distribution the "collective estimation" of the best fitting redshifts for the group of long bright gamma-ray bursts detected by BATSE experiment was found. ...

... We demonstrate through numerical simulations that model parameters estimated with our technique are essentially bias-free, even when the average number of counts per bin is 1. ... The IW technique avoids such biases by estimating through successive iterations, where for each iteration, j, , and the best-fit parameters are determined by minimization of . ... In our sample, we find that the minimum values and best-fit parameters converge after about 6 iterations. ...

First, we computed the mean errors of orbit parameters on the assumption of the linear connection of them with observation errors and then we compared obtained estimates with those resulting from the assumption of the nonlinearity of this connection. Secondly, we correlate orbital parameters and their errors obtained by the method of the least modulus with those obtained by the least-squares method. ...

Detecting Variations in Source Intensity for Poisson Data Y. Yu, XL. Meng, D. van Dyk, V. Kashyap, and A. Zezas Abstract The analysis of light curves is an especially challenging statistical task for low-count Poisson data: Variation in the source intensity may be shadowed by the Poisson variation of the counts. Here we discuss a class of statistical models that are designed to capture trends and autocorrelations in Poisson data that are collected over time. ... Example: A downward trend? . ...
