Data Science with Statistical Software R
Introduction and Basic Statistics with R
Date: Module wise
Venue: Godrej Hall, KAR Campus, Hyderabad + Video Conference.
Target audience:
Basic science researcher (PhD Students), all optometry faculty, Ophthalmology fellows/residence/DNB, BLSO student and anyone interested in BioStatistics.
Aims and Scope:
Data science is an exciting discipline that allows you to turn raw data into understanding, insight, and knowledge. The goal of “Data Science with R” is to help you learn the most important tools in R that will allow you to do data analysis. With the knowledge gained in this workshop, you will be ready to undertake your first very own data analysis.
· Introduction to statistical software R and basic data management with R.
· Applications of R to specific disciplines such as biology, epidemiology, genetics, and the ophthalmology.
· Combine statistical and machine learning techniques with R programming to analyze and interpret complex data.
· Graphical data analysis with R (ggplot2).
· Descriptive statistics, One and twosample tests, Regression and correlation Univariate and Multivariate data analysis with R
