## SERVICES

We are a team trained in mathematical modelling, statistical methodology, and computer programming. We offer consultation and data analysis services in academia and in industry. Services offered both online and in person.

We can assist businesses with data analytics by building dashboards and worksheets using Tableau, Power BI or other software. We also assist students and researchers with data analysis and mathematical modelling involving Tableau, R, R Studio, R Markdown, R Shiny, R Commander, Jamovi, Excel, Minitab, SPSS, AMOS, the Hayes PROCESS Macro, APA formatting, Power BI, IBM Analytics, Stata, SAS, Gretl, G-Power, Eviews, Data Analytics, Bayesian Statistics, Meta Analysis, Forest Plots, MATLAB, ArcGIS, Python and Jupyter Notebook.
