Most Probable Number and Other Microbial Enumeration Techniques
Calculates the Most Probable Number (MPN) to quantify the
concentration (density) of microbes in serial dilutions of a laboratory
sample (described in Jarvis, 2010 ).
Also calculates the Aerobic Plate Count (APC) for similar microbial
Added a 'CI_method' argument with a likelihood ratio confidence interval
option to mpn().
