... 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. ...

... Tools . ... In order to generate random numbers that follow a normal distribution, one first needs to create two uniform random numbers $u_{1}$ and $u_{2}$, in the range of 0 to 1. ... begin{equation*} g_{1} = \sqrt{-2 \ln(u_{1})} \cos(2 \pi u_{2}) \end{equation*} . ... Random numbers following a power law, $P(x) \propto x^{n}$, can be generated from a single uniform random number, $u$, in the range of 0 to 1 through the following transform : . ...

Documents to be distributed outside DMD division must also be issued according to the Technical Archive procedure . ... Several documents are also available as complete templates defined internally for DFS Department documentation (e.g. template for Test Plan, for Test Report, .. ... Define the internal document number as: dfs-volxx-yyy-zzzz . ... Document title, . ... Issue number (e.g. 1). ...

... Scheming arXiv:astro-ph abstracts almost an year never offered me an occasion that the fit of the Poisson distribution is tested in different ways, instead it is taken for granted by plugging data and (source) model into a (modified) ? ... Abstract: goodness-of-fit tests based on the Cramer-von Mises statistics are given for the Poisson distribution. ... 2 statistic for testing the goodness of fit in astronomy and this D statistics is considered as a two sided test approximately distributed as a ? ...

... Version 3.4.5 - 2005-06-28 (CB) ------------------------------- Ammended routine ommagnitude_mod in mssllib to set default polynomial coefficents to 1.0 and 0.0 (fixes SPR 3483 - mssllib version 2.43.12 has this fix) Also replaced source-list file in test directory with a more recent one to fix problem of negative magnitudes which cause a test-failure on one system. ... Adds a new column for the former correction. ... Version 2.2.2 2002-02-15 (CB) DEPEND file ammended to fix SPR 2757. ...

Neglecting the second derivatives matrix , we obtain the ``normal equations'' and the Gauss--Newton direction . This so--called Gauss--Newton method is intended for problems where is small. ... The algorithm implemented here is a modification of that Gauss--Newton method, that allows convergence even for rank deficient Jacobians or for large residuals. ...
