This textbook provides a comprehensive introduction to statistical
principles, concepts and methods that are essential in modern statistics
and data science. The topics covered include likelihood-based inference,
Bayesian statistics, regression, statistical tests and the
quantification of uncertainty. Moreover, the book addresses statistical
ideas that are useful in modern data analytics, including bootstrapping,
modeling of multivariate distributions, missing data analysis, causality
as well as principles of experimental design. The textbook includes
sufficient material for a two-semester course and is intended for
master's students in data science, statistics and computer science with
a rudimentary grasp of probability theory. It will also be useful for
data science practitioners who want to strengthen their statistics
skills.
