Description
Concepts and tools needed throughout the entire data science pipeline, from asking the right kinds of questions to making inferences and publishing results. Includes: Practical application of statistical computing through reading data into R, accessing R packages, writing R functions, debugging, profiling R code, and organizing and commenting R code. Basic data cleaning of an 'activity recognition dataset' of 30 subjects who wore waist-mounted smartphone sensors. Includes R code to load the raw dataset and processing instructions formalized in a markdown based codebook. Exploratory analysis techniques in R for summarizing data, including how to implement multivariate statistical techniques and use plotting systems in order to summarize high-dimensional data. Use of R tools to generate data analysis in a markdown document with a focus on providing results which can be easily reproduced. R markdown code integrates live R code, knitr and related tools. Collection of R scripts which employ fundamentals of statistical inference, including broad theories such as frequentists, Bayesian, and likelihood. Regression analysis performed on a collection of cars in order to explore the relationship between car features and fuel consumption. Includes special cases of the regression model, ANOVA and ANCOVA with analysis of dummy variable, multivariable adjustment, residuals and variability. Application of machine learning algorithms (decision tree, random forest and generalized boosted regression) using R, in order to explore personal activity data and predict the manner in which individuals completed particular exercises. A simple, yet scalable, web application built using Shiny, R packages, and interactive graphics, with a focus on automating statistical inference of a dataset related to passengers onboard the Titanic.
