![]() If you are a scientist you will see the relation between this method and entropy but that's not required. One thing you could add to list of methods to compare probability densities is Kullback–Leibler divergence. It provides the background on the tests as well as good examples. What I would suggest is if you would get the book, "Goodness-of-Fit-Techniques" by Ralph B. It looks like you have a clear understanding of all the available tests. I'd like to know if we can test whether there are significant changes in the tail-length distribution over the time course. Taking all the strings from the machines at different time points will give a time-varying distribution of special character tail lengths. ![]() Changing the environment the machines sit in may (or may not) change the tail-length distributions. Multiple machines generate strings of a fixed length with an added 'tail' (of an random integer number - say between 0 and 250 - of special characters). I know that the Kolmogorov-Smirnov test could be used (if corrected for the discrete ecdfs), and/or a chi-squared test, and other summary statistics could be compared (mean/variance/skewness &c), but is there a more powerful test along the lines of the Cramér–von_Mises test? There is unlikely to be much deviation across the whole of the discrete distributions, so I'd like the test to have as much power as possible, a situation that C-vM would be best suited for if the distributions were samples from a continuous distribution. adding the low pass and high pass responses obtained with the state variable filter to the summing amplifier makes a band stop filter can be seen in the below figure.I would like to know what the most powerful way of comparing two (or more) discrete distributions is.Note that this arrangement i like the bandpass category which we discussed in previous post with the difference is that resistance R3 has changed its position and R4 has inserted.Below figure indicate the circuit configuration of multiple feedback bandstop filter.So input frequency at the filter sweeps in the already adjusted range the response curvature is located at the display of spectrum analyzer.The spectrum analyzer is compulsory to elaborate oscilloscope which can be measured for a required frequency division rather than the general time setting.The swept-frequency generator generates a constant amplitude output signal whose frequency rises in a linear way among the 2 preset restrictions.diagram denoted as b indicates that how testing can be performed with the usage of the oscilloscope.In which swept frequency generator and spectrum analyzer is used. The circuit for this technique is shown in the below figure.This technique needed further elaboration testing devices than the previous technique, but this technique is efficient than the discrete point and provides correct response curvature.After measuring the specific values make a graphical representation of output voltage with the frequency.Measure every value of output voltage at each value of frequency.
