Use of Molecular Filter Membranes for Water Potability Control

“…This estimate, like many other maximum-likelihood estimates used in mathematical statistics, is biased and overestimates the true density (8). Descriptions of the techniques used in these have been given by Yee and associates (3) and by Presnell and associates (10). The amount of the correction depends on the number of tubes used in each dilution and decreases as the number of found that the densities obtained by MF methods averaged about 70 per cent of the confirmed MPN values.…”

“…Figure 1 is a correlation diagram of the coliform organism densities obtained in two of the investigations. Descriptions of the techniques used in these have been given by Yee and associates (3) and by Presnell and associates (10). Additional results of statistical analysis have been summarized by Thomas and Woodward (9).…”
