RyStats

A collection of statistical packages writtten in python.

Factor Analysis

Several factor analysis routines are implemented including:

1. Principal Components Analysis
2. Principal Axis Factoring
3. Maximum Likelihood
4. Minimum Rank

Rotation

1. Orthogonal / Oblique
2. Procrustes

Dimensionality Assessment

1. Parallel Analysis
2. MAP (Minimum Average Partial)

Miscellaneous

1. Polychoric Correlations

Plotting Tools

Plotting Tools require Bokeh and are made to be used within a Jupyter Notebook

Plot Functions

1. correlation_image: creates a heatmap of a correlation matrix
2. loading_image: creates a heatmap of a loadings matrix
3. scree_plot: plots the eigenvalues for dimensionality assessment
4. loading_table: creates a table that displays the loadings matrix

Dependencies

1. Numpy
2. Scipy
3. Bokeh (for plotting)

Installation

Via pip

pip install RyStats --upgrade

From Source
