Interactive Platform for Statistical Computing

Interactive Platform for Statistical Computing is a tool designed by Helikar Lab (Computational Biology @ University of Nebraska-Lincoln) to provide a free web-based platform to perform various statistical computations without having any knowledge of the high level programming languages, which is required for most statistical technologies. Most statistical technologies require users to be familiar with the command line and/or some type of a higher level programming language, making statistics less accessible to those who are not familiar with these technologies.

Development

The project was introduced as a part of Google Summer of Code (GSoC) in 2015.
The first version of the project utilizes the R server to build web-based interactive statistical analyses. Specifically, the following statistical functions were implemented in the first phase: Tabular data upload/export/visualization, descriptive statistics, t-tests (single-sample, independent sample, paired), graphing (2D/3D scatter plots, line, bar charts, box plots, histograms) and one/multi-way ANOVA.

As part of the second phase in GSoC 2016, the focus was to implement the statistical functions such as clustering, classification, time series analysis, regression models, correlation & covariance computations, heatmaps and various other plots.

GSoC 2018 (third and final phase in progress ...)
