One-Way Tables and Goodness of Fit

Key concepts:

  • One-way Frequency Table
  • Sampling Schemes (Models)
  • Pearson goodness-of-fit statistic
  • Deviance statistic
  • Pearson residuals


  • Learn how to compute the goodness-of-fit statistics
  • Understand how well an observed table of counts corresponds to the multinomial model Mult(n, π) for some vector π.
  • Introduce the FREQ procedure in SAS and the prop.test and the chisq.test in R
