Fig. 4From: Mean and variance of ratios of proportions from categories of a multinomial distributionThe results for mean for the data from Fig. 3. The simulation data for original ratios Z0 (squares) are compared with models: the Taylor-series model (solid line) and corrected modified ratio model (dashed line). Observe the uncorrected modified ratio model (dash-dot line) which exactly models the modified ratios Z1 (red circles) in all casesBack to article page
