The term "probability distributions" refers to mathematical functions that describe the probabilities of various possible outcomes of a random experiment. They indicate how likely it is for a random variable to take on certain values. Probability distributions are central concepts in statistics and probability theory and are applied in many fields, including finance, natural sciences, engineering, and social sciences.

Typical software functions in the area of "probability distributions":

- Distribution Calculation: Automated calculation of various probability distributions, such as normal distribution, binomial distribution, or Poisson distribution.
- Visualization: Creating charts and graphs to visualize probability distributions.
- Parameter Estimation: Determining the parameters of a distribution based on given data.
- Simulation: Generating random data based on a defined probability distribution.
- Fit Analysis: Fitting probability distributions to observed data and evaluating the goodness of fit.
- Statistical Tests: Conducting tests to verify hypotheses about probability distributions, such as the Chi-square test or Kolmogorov-Smirnov test.
- Distribution Functions: Providing functions for calculating distribution values, density functions, and cumulative distribution functions (CDFs and PDFs).
- Data Import/Export: Importing and exporting data for probability distribution analysis.
- Reporting: Creating reports and documentation of analysis results.
- Custom Distributions: Defining and analyzing custom probability distributions.

Examples of "probability distributions":

- Normal Distribution: A continuous distribution often used to model natural phenomena.
- Binomial Distribution: A discrete distribution that describes the number of successes in a fixed number of Bernoulli trials.
- Poisson Distribution: A discrete distribution that describes the number of events in a fixed interval of time or space.
- Exponential Distribution: A continuous distribution that describes the time between events in a Poisson process.
- Uniform Distribution: A distribution where all outcomes are equally likely.
- Student's t-Distribution: A distribution often used in hypothesis testing when the sample size is small.
