Compare The Functions From Different Studies

Overlaid consonance functions from two studies, comparing their p-value curvesOverlaid likelihood functions from two studies, comparing their relative likelihood curves


Export Tables Easily For Word, Powerpoint, & TeX documents

Example table of interval estimates at several confidence levels, generated by curve_table()
