Abstract

mountainplot produces mountain plots for variables in a varlist as proposed by Monti (1995), and mountain plots for differences between variables in a varlist as proposed by Krouwer and Monti (1995). A mountainplot is a graphical representation of an empirical cumulative distribution function in which percentile values above 50 are "folded" (i.e. subtracted from 100 in order to produce a reverse ordering). The resulting graphic resembles a mountain where the peak is approximately at the median. Monti (1995) suggests that mountain plots allow the user to perform the following: (1) determine the median, (2) determine the range, (3) determine the central or tail percentiles of any magnitude, (4) observe outliers, (5) observe unusual gaps in the data, (6) examine the data for symmetry, (7) compare several distributions and (8), visually gauge the sample size. Krouwer and Monti (1995) propose creating a mountain plot as a complementary to the Bland and Altman plot (Bland and Altman 1986). Here, the mountain plot represents the percentile difference between a new test and a reference test (Y-axis). This percentile difference is then plotted against the difference between the two tests (X-axis).
