Introduction One of the many reasons why people do not like R is because you find more than one way of performing an operation. But i woul like to say this could be an advantage as every possible way can have more advantage for a given task .

Introduction ggplot2 is an R package by Hadley Wickham and Winston Chang that implements Wilkinson’s Grammar of Graphics. The emphasis of ggplot2 is on rapid exploration of data, and especially high-dimensional data.

Introduction Over the years , the debate has always been …which one is better for data science ,R or Python? . I say it all depends with where you are coming from and as long as you get the job done .

Introduction Goal for Today Introduce you to R and Rstudio. What Are R and Rstudio? What Is R? R is an open source programming language with origins in C and FORTRAN.

What do we mean by the linear model? Regression is the workhorse of statistics. It allows us to model a response variable as a function of predictors plus error. Linear regression is what most people first encounter in statistics.

Every time some operations have to be repeated, a loop may come in handy. Loops are good for: Doing something for every element of an object; Doing something until the processed data runs out; Doing something for every file in a folder; Doing something that can fail, until it succeeds; Iterating a calculation until it reaches convergence.

Multinomial If we have more than two categories or groups that we want to model relative to covariates (e.g., we have observations \(i = 1,\cdots,n\) and groups covariates \(j = 1,\cdots,J\)), multinomial is our candidate model
