LeOra Software Company developed computer software in the late 1980's for analyzing quantal response bioassays using probit or logit regression analyses. The software was called PoloPC, and it was written in the ancient language of Fortran. The software was later updated to PoloPlus software written in C. The newest version of the software was written in Java by a team of 5 programmers with a passion for quantitative analyses and problem solving.
The Original PoloPlus software Is available for purchase. It is mounted on a USB drive , so it works well with any Windows version. Sorry, not available for Mac.
