Question

Which of the following count the number of good cases when doing pairwise analysis?

(a) count.pairwise

(b) count() +

(c) anova.para()

(d) count.poly()

I have been asked this question during an interview.

My enquiry is from Linear Regression topic in division Commands, Packages, Visualizing Data and Linear Regression of R Programming

Answer 1

Right choice is (a) count.pairwise

For explanation I would say: Pairwise comparison generally is any process of comparing entities in pairs to judge which of each entity is preferred.
