Software Package for Data Exploration, Univariate Analysis, Multivariate Analysis and Time Series Analysis

Current Brodgar version: 2.7.5 (March 2017)

The statistical package Brodgar allows the user to carry out a range of statistical techniques in a Click-and-Go style. The package has an interface to R but also contains a couple of statistical methods not available in R, e.g. dynamic factor analysis, MAFA, chronological clustering.

The following techniques are available in Brodgar

  • Data exploration: Boxplots, (multi-panel) Cleveland dotplots, (multi-panel) histograms, (multi-panel) scatterplots, pairplots, design and interaction plots.
  • Univariate analysis: Regression, GLM, GAM, mixed modelling, GLS, univariate regression trees. Power analysis
  • Multivariate analysis: Principal component analysis, correspondence analysis, redundancy analysis, canonical correspondence analysis, MDS, NMDS, ANOSIM, Mantel test, clustering techniques.
  • Time series techniques: Dynamic factor analysis, MAFA, chronological clustering, auto-correlation functions.

 

Due to other commitments (converting all our courses to online courses due to Covid, consultancy, and book writing, we are currently not able to update Brodgar. We, therefore, decided to make it available for free for 2020 and 2021. The license codes are as follows:

Brodgar compliance statement on R GNU license

The software package R is distributed under the GNU general public license. Brodgar, which is not distributed under the GNU license, creates ascii files containing R script commands which are sourced into the binary version of R (using the BATCH mode). Although Brodgar is linked to R, it does not contain it. The user will need to (i) download a compiled version of R, (ii) install it and (iii) tell Brodgar where it can find R. Hence, R and Brodgar are two different packages (Brodgar is the shell and R the compiler) which are an arm length apart.  As a consequence, Brodgar complies with the GNU license. See http://www.gnu.org/copyleft/gpl.html for details.
