Biologist, data scientist, R programmer

I have more than 10 years experience conducting analyses in R, SPSS, Excel, QGIS and LibreOficce. I am experienced with R programming, descriptive statistics, T-tests, nonparametric statistics (Kruskal-Wallis and Wilcoxon signed rank tests), hypothesis testing using bootstrap and permutations, correlation coefficients, Chi-squared test, regressions (linear, multiple, logistic), ANOVA, principal components analysis, factor analysis, discriminant analysis, classification trees, interpolation, time series, and Shiny web applications. I also can create a wide range of figures for data visualization (e.g., maps, box plots, bar charts, heatmaps, histograms, biplots, cloudplots, bubble plots, circle plots countor plots, plots over maps, summary plots, lineplots, etc.), depending on what is required. I am comfortable working in Windows and Ubuntu Linux environments. My interests and previous experience include data analysis for ecology research, biodiversity, environmental pollution, physiology, genetics, analytical chemistry and experimental design. I have a bachelor’s degree in biology, an MSc in biological sciences and a PhD in oceanography. Currently I work in data analysis and statistics, and as data scientist, I enjoy solving complex and interesting tasks. Please feel free to contact me. Thank you.

"WOW, César was amazing and great!! He was flexible and helpful beyond expectations. He explained all the work carefully as I am a novice, and his attention to detail throughout the work is laudable! He is in full command of his craft, an expert in regression analysis and R modeling. He understood the work quickly and created diagrams to show he understood the work and how he would address it. When we encountered issues with the model, he was able to quickly find an alternative solutions. Well mannered and overall great person. 100/10 Recommend him! Thank you César!"
