Exploring Operations Research with R (eBook, ePUB)

• Format: ePub

Produktbeschreibung

The core aim of the book is to provide a self-contained introduction to R (both Base R and the tidyverse) and show how this knowledge can be applied to a range of OR challenges in the domains of public health, infectious diseases, and energy generation, and so provide a platform to develop actionable insights to support decision making.
