Introduction to Statistics
The book Introduction to Statistics by W. Härdle, S.Klinke and B. Rönz has been published in 2015 by Springer Verlag (paper/pdf/epub).
It covers all the topics found in introductory descriptive statistics courses, including simple linear regression and time series analysis, the fundamentals of inferential statistics (probability theory, random sampling and estimation theory), and inferential statistics itself (confidence intervals, testing).
