What You’ll Find In This zyBook:
More action with less text.
- An exceptionally student-focused introduction to regression analysis.
- Traditionally difficult topics are made easier using animations and learning questions.
- Python coding environments are provided throughout to allow students to experiment.
- Commonly combined with “Applied Statistics with Data Analytics” with numerous configurations possible.
The zyBooks Approach
Less text doesn’t mean less learning.
This zyBook builds on the techniques introduced in linear regression and provides the tools needed to analyze the relationship between two or more variables. Ideal for students enrolled in a second applied statistics course, Applied Regression Analysis dives deeper into model selection and evaluation. The following questions are answered: Which variables should be included or removed to better predict the target variable? Are the conditions for a specific technique satisfied? Which transformations can be performed on the data when certain conditions are violated? Additional topics covered are time series, Monte-Carlo methods, bootstrapping and randomization, and non-parametric statistics.
