12.11 Simply Growth
is a windows program to analyse growth curves from length and/or
The program will fit and plot von Bertalanffy, Gompertz and Logistic growth curves to
your data. These curves are used to model the growth of a wide variety of organisms
but are not simple to fit, as they require the estimation of a number of parameters by
non linear regression.
Particular care has been taken to allow data to be quickly and easily imported from
spreadsheet programs such as Excel and the plots can be exported in a variety of
12.12 Simply Probits
is a windows program to estimate lethal or environmental
concentrations using toxicity data.
The program offers two types of analysis.
Lethal dose calculations: a probit analysis of the survival of organisms exposed to a
range of concentrations. Conforms to ISO/DIS 146609.
Growth analysis: studies the inhibition in the growth of organisms exposed to
different levels of a compound.
Conforms to ISO 10253 .
