The demo program is coded using C#, but you should have no trouble refactoring the code to another language, such as JavaScript or Python. All the demo code is presented in this article and is also available in the accompanying download. The Demo Program Structure The overall structure of ...
After rescaling, multiple well-established goodness-of-fit procedures and statistical tests are available. We demonstrate the application of these methods both to simulated data and real population spiking in rat hippocampus. We have made the MATLAB and Python code used for the analyses in this ...
Right, so it's safe to assume that the population proportions are not all equal. But precisely how different are they? We can express this in a single number: theeffect size. Effect Size - Cohen’s W The effect size for a chi-square goodness-of-fit test -as well as thechi-square ...
