BF_sim: Example simulation from Brown and Forsythe (1974)

Description

Example results from the Brown and Forsythe (1974) article on robust estimators for variance ratio tests. Statistical tests are organized by columns and the unique design conditions are organized by rows. See BF_sim_alternative for an alternative form of the same simulation. Code for this simulation is available of the wiki (https://github.com/philchalmers/SimDesign/wiki).
