Allometric genetics:
in a factorial with results expressed in logarithms the linear effects
are the coefficients in the allometry expression
--Luiz Torres de Miranda and Luiz Eugenio Coelho de Miranda
Since MNL 55:18-19 we have tried by allometrical genetics to develop algorithms
more biologically minded. To begin to achieve this it is necessary to transform
the original data in logarithms, but generally after this there is no change
of procedure. This report deals with how the data could be analysed and
interpreted. The solution of a factorial is achieved as:
Equation
Part 1
Equation
Part 2
Taking the calculated values a and b in the factorial, we calculate
2(1-a-b) as the allometric
origin A of the design, and F=A+ax+by
is the antilogarithmic solution of the table where 2a+2b
is for a, 2a for b,
2b for c and A is d, having no coefficient beyond
1 itself. This works at least with data expressed up to 100%.
