BF_sim_alternative: (Alternative) 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 and distributions are organized by columns and the unique design conditions are organized by rows. See BF_sim for an alternative form of the same simulation where distributions are also included in the rows. Code for this simulation is available on the wiki (https://github.com/philchalmers/SimDesign/wiki).
