R-regression-basics-tutorial

• Regression analysis and modeling by R launguage is really fun.
• This repository have only data analysis and regression modeling for 1 dataset 'prestige'. The dataset is quite small. But even with this small data, you can analyze/model in various ways. That's the fun.
• The analysis and modeling covered here is (just example):
  • data exploration by Cleaveland dotplot and correlations.
  • data transformation
  • ordinary linear regression
  • model diagnostics
    • default plot
    • assess residuals
    • confidence interval
    • main effect plot
  • model update
    • model interactions
    • identify influential data by various method
    • variable selection (exhaustive and stepwise)
  • model comparison
  • model understanding
    • conditional effect plot
    • full model plot
  • robust regression
  • multimodel inference
• This is just ordinary linear regression (with some tweaks). If you would like to try more, here would help:
