RyStats

A collection of statistical functions written in python. Many of these functions can be accessed without downloading any software at GoFactr

Factor Analysis

Several factor analysis routines are implemented including:

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

Rotation

1. Orthogonal / Oblique
2. Procrustes

Dimensionality Assessment

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

Correlations

1. Polychoric Correlations
2. Polyserial Correlations
3. Biserial Correlations

Inferential Analysis

1. Linear Regression
2. Logistic Regression
3. One/Two-way Anova
4. T-Tests
5. Mediation

Survey Utilities

1. Reverse Scoring
2. Cronbach's Alpha
3. McDonald's Omega

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

pip install . -t $PYTHONPATH --upgrade

Unittests
