Classic Statistician with R expertise
$70.00/hr
I love exploring and making sense of data with R and I constantly use packages like ggplot2, plotly, (for data visualizations), forecast, ts, (for time series analysis), lme4, (for linear mixed effect modelling), etc. I can help out with all sorts of statistical analysis and modelling, ranging from basic T-tests and ANOVAs to linear mixed effect models, time series analysis, logistic regressions or even more advanced machine learning tasks.
I have a bachelor's degree in statistics and a master's degree in applied mathematics, coupled with years of experience in statistical data analysis and developing solutions in R. I have developed interactive web-based data applications using the shiny framework in R and I have created lots of dynamic reports using Rmarkdown. I have also written technical reports and created blogs with the bookdown and blogdown packages respectively in R. Sometimes, I find myself using Python, IBM SPSS, and Tableau.
I am currently doing a Ph.D. in Statistics, and I research about fast and scalable outlier detection and visualization methods for functional data. I am also the author and maintainer of the fdaoutlier R package on CRAN. Check out my musings at statimatics.com (built using R) and feel free to reach out if you would like to collaborate on a project.
