1. Bias-Free Parameter Estimation with Few Counts, by Iterative Chi-Squared
... 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. ...

3. Dependence on the Scenario Parameters and Initial Distributions
... Calculations of at least two runs with different values of a parameter are required in order to discover to what extent the results depend on the , if at all. ... In order to study how the final statistical distributions depend on the initial functions, the method of Green functions is used. ... Then we can restore any distribution on this parameter (with a certain accuracy) by summing the results for each interval with the appropriate weight. ...

A simple way to graphically present the results of a TSA is to plot the test statistics S against its parameter or l , depending on whether the analysis was performed in the frequency or time domain. ... Examples of statistics used in the time domain are covariance and correlation functions. The correlation of a signal with itself or with another signal produces maxima in these functions at particular lags. ...
