Abstract
A 1-pass computer programme in Fortran is presented that produces least squares estimates and standard errors for the constants of the "Multi Hit" curve. The mathematical expression for the curve is S=l [1 exp( kD)]n where S is the proportional response to a dose D, and k and n are constants to be estimated. The programme permits the choice of 3 weighting factors and accepts data entered as individual values or as means with associated weights.Keywords
