IQR = Interquartile range These equations give you two values, or “fences“. You can think of them as a fence that cordons off the outliers from all of the values that are contained in the bulk of the data. Example question:Use Tukey’s method to find outliers for the following set ...
iqr = np.subtract(*np.percentile(x, [75, 25])) than making two calls to percentile: In [8]: x = np.random.rand(1e6) In [9]: %timeit q75, q25 = np.percentile(x, [75 ,25]); iqr = q75 - q25 10 loops, best of 3: 24.2 ms per loop In [10]: %timeit iqr = np.su...

Non-parametric tests, like Mann-Whitney, assign numeric ranks to all the observations in the groups, then test whether the sums of ranks in the groups are different. So, AFAIK, we cannot conduct a non-parametric test just by knowing the median+IQR. Share Cite Improve this answer Fol...

Python Profilers, like cProfile helps to find which part of the program or code takes more time to run. This article will walk you through the process of using cProfile module for extracting profiling data, using the pstats module to report it and snakev
