Non-paramtric tests & discrete data

What question do you have?

Today

  • What to do if the parametric assumptions violated
  • Non-parametric equivalents
  • Discrete data (chisquare, loglinear model)

Non-parametric tests

Non Parametric tests

Parametric assumptions

  • Independence of errors
  • Homogeneity of variance
  • Normality

Independence of errors
