New
Statistics Package
The new Statistics package contains a collection of functions
and interactive tools for mathematical statistics and data
analysis. It supports a wide range of common statistical
tasks, such as quantitative and graphical data analysis,
symbolic manipulation of random variables, simulation,
and curve fitting.
Features include:
- Over 35 continuous and
discrete probability distributions, as
well as tools for creating new distributions.
- Tools for creating and
manipulating random variables as well as
functions for computing their densities,
moments, generating functions, and other
quantities.
- A wide range of functions
for computing descriptive statistics. This
includes location, dispersion and shape
statistics, moments and cumulants, as well
as several data summary and tabulation
commands.
- Statistical plots including
box plots, bar charts, histograms, probability
plots, and scatter plots.
- Optimized algorithms
for simulating all supported distributions,
as well as tools for creating custom random
number generators, and parametric and non-parametric
bootstrapping.
- Tools for fitting linear
and nonlinear models to data points and
performing regression analysis.
- Tools for manipulating
likelihood functions, maximum likelihood
estimation, kernel density estimation,
and bootstrapping.
- Tools for manipulating
statistical data such as data smoothing
functions for moving averages, exponential
smoothing, and linear filters.
- Common tools for performing
hypothesis testing and inference, including
several parametric and non-parametric tests.
