Almost there. Remaining downstream functions to fix:

• [x] meta_analyse_datasets() use same approach as n_max/n_min/VZ_cutoff argument matching strategies to deal with different outcome variables
  • [x] calculate_deviation_score()
  • [x] box_cox_transform()
  • [x] fit_sorensen_glm()
• [ ] Check make_viz works as expected after updates on branch

huge push! make_viz() fns to check:

• [x] get_MA_fit_stats()
• [ ] gg_forest()
• [ ] poss_viz_funnel()
