... 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. ...

. Intervals of available data are coded by blue color. To read availability charts user should know the descriptor ("name") of the KP subset of interest. Table annotations include also number of version for each subset. Plot resolution is exactly one pixel per hour. Data are considered as available if at least one data point is present during that hour.

... Posts tagged ?parameter estimation? ... Leccardi & Molendi (2007) have a paper in A&A ( astro-ph/0705.4199 ) discussing the biases in parameter estimation when spectral fitting is confronted with low counts data. Not surprisingly, they find that the bias is higher for lower counts, for standard chisq compared to C-stat, for grouped data compared to ungrouped. ...
