      I just like for a sample, we can speak of percentiles for a r.v. I for instance: the 5% percentile is the k such that 5% of the distribution falls below k I in Scipy it's called ppf : my_rv.ppf(0.05) 10 15 20 25 30 35 40 0.00 0.05 0.10 0.15 0.20 0.25 5% percentile

      Given a data sample, we use the fit method of SciPy to extract the parameters of that distribution that best fit the data. We repeat this for all available distributions. Finally, we provide a summary so that one can see the quality of the fit for those distributions Here is an example where we generate a sample from a gamma distribution. 4 ...

      Development of EmoViz was done primarily on Linux and Linux-based systems, so configurations will be given in this context. The instructions assume a Debian-based distribution, such as Ubuntu, which uses the ‘apt’ package manager. If your computer is running a different Linux-based operating system, you may use the default package manager.

      2) Variables were assessed for normality visually, and by D’Agostino-Pearson testing. K-means favours identification of spherical shaped clusters, meaning that left or right skewed variables may lead to poorly captured groups. Log transformation was performed on variables that conformed to a natural power law distribution.
