Calculates the two way ANOVA, fixed effects model, mixed effects model and random effects model
7.1 The Interactive Two-Way ANOVA Model. The model below includes two fixed-effects factors, an interaction term between the factors, and assumes a balanced design with \(n>1\) replicates per treatment combination. \[Y_{ijk} = \mu + \alpha_i + \beta_j + \gamma_{ij} + \epsilon_{ijk}\]
3 gru 2011 · When reporting a two way 2 x 3 mixed ANOVA I have recently heard that the interaction effect should only be reported if the two main effects are significant (APA style). Is this correct?
