Random randn
Tīmeklis2024. gada 23. aug. · numpy.random.randn. ¶. Return a sample (or samples) from the “standard normal” distribution. If positive, int_like or int-convertible arguments are provided, randn generates an array of shape (d0, d1, ..., dn), filled with random floats sampled from a univariate “normal” (Gaussian) distribution of mean 0 and variance 1 … Tīmeklis2024. gada 1. nov. · The function numpy.random.randn returns values from the standard normal distribution, which can be anything between negative and positive infinity, so there's no max or min. These values are distributed along the "bell curve" centered at 0, and are exponentially less likely to occur the farther you get from 0.. …
