We own several copies of POLO Plus version 2.0 and have found a problem with the software. When running a data set with doses converted to logarithms (standard), all is well in the printed 'Summary' and 'Results' and 'Plots'. However, when running the same data set with doses not converted to logarithms, the calculations for "lethal dose ratios" are incorrect and sometimes printout only asterisks ******
.
Please advise ASAP. I have lots of data sets to run.
