pystats_norm

pystats_norm is a lightweight statistical package that performs normal distributions calculations. Inspired by the simplicity and functionality of statistical tools in base R, pystats_norm provides a focused set of functions for generating random samples, calculating cumulative probabilities, determining quantiles, and evaluating probability density functions. This package hopes to serve statisticians, data scientists, and researchers looking to derive meaningful insights from their data.

It features the following core functions:

1. rnorm: Generate random samples from a normal distribution
2. pnorm: Compute probabilities for a given quantile (cumulative distribution function)
3. qnorm: Calculate the quantile (inverse of cumulative distribution function) for a given probability
4. dnorm: Evaluate the probability density function.

Functions

rnorm(n, mean=0, sd=1):

Generates a NumPy array of length n containing normally distributed random variables with mean equal to mean and sd equal to sd.

pnorm(q, mean=0, sd=1, lower_tail=True):

Computes the cumulative distribution function (CDF) for a given quantile.

qnorm(p, mean=0, sd=1, lower_tail=True):

Computes the quantile (inverse CDF) for a given probability.

dnorm(x, mean=0, sd=1):

Calculates the Probability Density of the normal distribution for a given value

Python Ecosystem Integration

pystats_norm is designed as a lightweight and intuitive package for normal distribution calculations. While similar functionality exists in libraries such as SciPy and NumPy, pystats_norm focuses exclusively on normal distributions, offering simplified functions with user-friendly syntax designed for statistical analysis. By providing well-documented and focused functionality, it serves as a niche yet essential tool in the Python ecosystem.
