Abstract: The application of probit analysis to quantal-response data

(i.e. data from experiments of the "go/no go" variety) is well established

and is discussed in great detail by Finney (1952). The computational

procedure is straightforward but, as conventiorudIy performed by desk

calculator, very tedious and time consuming. This takes only minutes to

produce a probit line equation to a predetermined accuracy by means of

repeated iteration.
