Data Analysis with R by Coursera
This course is part of multiple programs.
Course Highlights
- Prepare data for analysis by handling missing values, formatting and normalizing data, binning, and turning categorical values into numeric values.
- Compare and contrast predictive models using simple linear, multiple linear, and polynomial regression methods.
- Examine data using descriptive statistics, data grouping, analysis of variance (ANOVA), and correlation statistics.
- Evaluate a model for overfitting and underfitting conditions and tune its performance using regularization and grid search.
