nb-probability 0.1.0

A package for Gaussian and Binomial distributions

nb_probability Package

A Python package for working with Gaussian and Binomial distributions. This package provides classes and methods to calculate and visualize Gaussian and Binomial distributions.

Features

• Calculate mean and standard deviation for Gaussian and Binomial distributions
• Compute probability density functions
• Plot distributions using Matplotlib
• Read data from files and update distribution statistics

Installation

You can install the package using pip:

pip install nb_probability

Usage Here are some examples of how to use the package:

Gaussian Distribution The Gaussian class provides methods to calculate and visualize Gaussian distributions.

from probability_distributions import Gaussian

Create a Gaussian distribution

gaussian = Gaussian(mean=0, stdev=1)

Calculate mean and standard deviation

mean = gaussian.calculate_mean() stdev = gaussian.calculate_stdev()

Print mean and standard deviation

print(f'Mean: {mean}, Standard Deviation: {stdev}')

Plot the Gaussian distribution

gaussian.plot_histogram_pdf()

Methods calculate_mean(): Calculates the mean of the data set. calculate_stdev(sample=True): Calculates the standard deviation of the data set. read_data_file(file_name, sample=True): Reads data from a file and updates the mean and standard deviation. plot_histogram(): Plots a histogram of the data. pdf(x): Calculates the probability density function for a given point. plot_histogram_pdf(n_spaces=50): Plots the normalized histogram and probability density function. add(self, other): Adds two Gaussian distributions. repr(): Returns the string representation of the Gaussian distribution. Binomial Distribution The Binomial class provides methods to calculate and visualize Binomial distributions.

Example

from probability_distributions import Binomial

Create a Binomial distribution

binomial = Binomial(prob=0.5, size=20)

Calculate mean and standard deviation

mean = binomial.calculate_mean() stdev = binomial.calculate_stdev()

Print mean and standard deviation

print(f'Mean: {mean}, Standard Deviation: {stdev}')

Plot the Binomial distribution

binomial.plot_bar_pdf()

Methods calculate_mean(): Calculates the mean of the Binomial distribution. calculate_stdev(): Calculates the standard deviation of the Binomial distribution. replace_stats_with_data(file_name): Reads data from a file and updates n, p, mean, and stdev. plot_bar(): Plots a bar chart of the data. pdf(k): Calculates the probability density function for a given number of positive outcomes. plot_bar_pdf(): Plots the probability density function. add(self, other): Adds two Binomial distributions with equal p values. repr(): Returns the string representation of the Binomial distribution.
