We do not need true randomness in machine learning. Instead we can use pseudorandomness. Pseudorandomness is a sample of numbers that look close to random, but were generated using a deterministic process. Shuffling data and initializing coefficients with random values use pseudorandom number ...
The visual approaches perform better than statistical tests. For example, the Shapiro-Wilk test has low power for small sample size data and deviates significantly from normality for large sample sizes (say n > 50). For large sample sizes, you should consider to use QQ-plot for normality assu...
