Models for Factors with Quantitative Levels

  • Ronald Christensen
Part of the Springer Texts in Statistics book series (STS)


Just as in analysis of variance, if the levels of some factors are associated with quantitative values, these values can be used in the analysis. For example, in a two-factor ANOVA where factors are two kinds of fertilizer and levels are different quantitative amounts of fertilizers, an ANOVA would often examine linear and higher order contrasts in the main effects and polynomial contrasts in the interaction (e.g., the linear-by-linear contrast).
