Introduction to R and Statistics
From Thursday 24 January 2019
To Saturday 26 January 2019
Organized by: Laurențiu Leuștean and Alina Tigău

The Research Institute of the University of Bucharest (ICUB) announces the second workshop within the series ‘Introduction to R and Statistics’, which is to take place between January 24-26, 2019.

‘Introduction to R and Statistics’ is a series of workshops hosted by ICUB, whose aim is to support researchers unfolding experimental work within various fields to get acquainted with and become proficient in using statistical methods in order to design and analyse their experiments. The lectures and discussions will dwell on various topics on statistics, associating these with corresponding topics on R, a programming language which has been rapidly gaining popularity in statistics and data science in the past few years, and which has lately become the norm for most research fields worldwide.

This second round of lectures and discussions have been scheduled for January 24-26 at the Sinaia Zoological Station of the University of Bucharest and aims at bringing together young researchers and PhD students from various faculties of the aforementioned institution. The lectures will be delivered by Adrian Dușa, professor at the Faculty of Sociology and Social Assistance of the University of Bucharest.

Associated to the statistics topics, the following topics on R will be touched upon:

1. Types of objects in R: vectors

2. Types of objects in R: matrices and data frames. Importing data

3. Functions and formal arguments with a focus on those concerning probability calculus. The dbinom() function in R base and dbinoms() function in the ‘statistics’ package (to be handed out before the training)

4. The functions: sample(), dnorm(), pnorm(), qnorm() in the R base

5. Applications of the aforementioned functions and the daria() and dariat() functions from the ‘statistics’ package

6. The t.test() function and its arguments

7. The prop.test() function and its arguments; the pwr.p.test() function for proportions and the pwr.t.test() function for averages from the „pwr” package.
