tab, choose FUNCTDENT as the categorical variable for which we would like to have SPSS calculate the means of NUM_DIAGNOSTIC. When you have arrowed FUNCTDENT into the box at the upper right of the window, select the Contrast as Pairwise, to get comparisons of the number of diagnostic services for each level of FUNCTDENT.

$\begingroup$ So to clarify: My question is: How to run pairwise comparisons in non-parametric ANCOVA in R/SPSS? I know how to run them after a non-parametric ANOVA (Kruskal-Wallis test) in R/SPSS: Dunn post hoc test with bh corrections. Thank you for your help. $\endgroup$ – Shimano Oct 31 '17 at 16:49

Multiple Comparisons. Here are the results of all pairwise comparisons using Tukey's HSD. I find the "Matrix of Ordered Means" described earlier as an easier way of working out which means are significantly different to which other ones. But all the information is here (plus extra that you don't really need).

Additional insight is provided by the Bonferroni-corrected pairwise comparisons, which indicate that the means for Before and After are significantly different, while none of the other comparisons are signficant. The profile plot is of assistance in the visualization of these contrasts. See Figures 7-9 and 7-10.

If a quadratic trend is selected SPSS will test for both linear and quadratic trends. Figure 2: Dialog box for conducting planned comparisons The lower part of the dialogue box in Figure 2 is for specifying planned comparisons. To conduct planned comparisons we need to tell SPSS what weightings to assign to each group.

estimates stationary, adjusting for multiple comparisons by making the intervals wider (or, equivalently, adjusting the p values corresponding to intervals of ﬁxed width). In this way, multilevel estimates make comparisons appropriately more conservative, in the sense that intervals for comparisons are more likely to include zero.

•SPSS output 14 The Levene’s test is about the equal variance across the groups. p = .137, means homogeneous variances across four groups. One-way ANOVA •SPSS output 15 There was a significant difference across the three routes F (2,21) = 27.45, p = .000

The second one will create a pairwise comparison for the drive main effect; the confidence interval will be adjusted by the Sidak procedure. It looks as though the third /EMMEANS subcommand will create a pairwise comparison for the drive*reward interaction. But it won't yet do that, it is a future feature of GLM.

Calculate pairwise comparisons using the Bonferroni correction; In the section on all pairwise comparisons among independent groups, the Tukey HSD test was the recommended procedure. However, when you have one group with several scores from the same subjects, the Tukey test makes an assumption that is unlikely to hold: The variance of ...

Jan 31, 2020 · A t-test can only be used when comparing the means of two groups (a.k.a. pairwise comparison). If you want to compare more than two groups, or if you want to do multiple pairwise comparisons, use an ANOVA test or a post-hoc test.

The problem we have is that we have three level: Watching vs Reading vs Thinking @ Low, Watching vs Reading vs Thinking @ High. In the old school approach, we first have to run an F-test (one-way ANOVA) at each level of Level of Exposure and run pairwise or contrasts to follow up if the One-way was significant.

In level 1 you will have one comparison matrix corresponds to pair-wise comparisons between 4 factors with respect to the goal. Thus, the comparison matrix of level 1 has size of 4 by 4. Because each choice is connected to each factor, and you have 3 choices and 4 factors, then in general you will have 4 comparison matrices at level 2.
