Conway, G. R., Glass, N. R., & Wilcox, J. C. (1970). Fitting Nonlinear Models to Biological Data by Marquardt´s Algorithm (Vol. 51).
Zusammenfassung: Equations describing biological phenomena frequently have parameters entering nonlinearly. A highly efficient method for detemining the values of parameters in such equations that will give the best least-squares fit to a set of data is Marquardt´s algorithm. A step-by-step derivation of the algorithm is given in terms that require only the knowledge of elementary calculus and matrix algebra. As an example, the method is used to fit the logistic equation to a set of data.

Dahlberg, M. L. (1978). Computer program for analysis of the homogeneity and goodness of fit of frequency distributions, FORTRAN 4 (Vol. 76).
Zusammenfassung: A computer program was developed which forms frequency distributions from length measurements and then calculates a chi-square statistic which is used to test the homogeneity of the frequencies for the purpose of pooling. Output includes listing of arithmetic mean, variance, standard deviation, standard error of the mean, total sample size, and chi-square statistic of goodness of fit for individual groups and for the pooled frequency distribution. Histograms of all frequency distributions are produced as full-page printer charts, scaled if necessary to 50 units by up to 100 class intervals. The pooled frequencies and class midpoints are punched on cards to facilitate additional analyses. The program was developed on an IBM 360/65 OS System and required 56,811 bytes of storage.
