mean argument in prec_mean (see #113)perc_meandiff calculated the degree of freedom incorrectly for equal variance differences (see #106)prec_mean and prec_meandiff that the former is suitable for paired mean differences. Comparable changes in the shiny app.prec_sens and prec_spec regarding the n in the outputprec_icc regarding assumption of no interaction between rater and subject (see #97)prec_lr (prec_pos_lr, prec_neg_lr) to simplify positive/negative LRsprec_lraddition of function for Cohen's kappa
update shiny app to include kappa
POSSIBLE BREAKING CHANGE: arguments in prec_rateratio renamed from *_exp and *_control to *1 and *2 for consistency with other functions
prec_sens and prec_spec allow prev and conf.width
multiple notes allowed in print method
add contributing guidelines
prec_sens_spec removed. Confidence intervals and sample sizes are quite different to other methods. A two step approach using prec_sens and prec_spec is instead recommended
addition of various tests
addition of rate ratio method
