What statistical tool should i use if i want to relate shell dimensions & shell voulme to tissue weight, etc.?

Question

i need this for a study about a bivalve, ireally need your help!
tnx!

the shell dimensions are:
length
width
height

i want to relate the dimensions plus shell volume
to tissue weight and live weight.

i really need a SCIENTIFIC PAPER
but a method could me useful
if u explain it..

please...thanks thanks thanks!!!

Answer 1

You can approximate the volume of the shell with the volume of an ellipsoid,
V = (4/3)π(length)(width)(height)
If you have a table of known volumes along with their respective dimensions, you can run a three-dimensional regression to estimate the constant represented by (4/3)π by substituting logarithmic forms:
ln(V) = a + bln(L) + cln(W) + dln(H)
Relating tissue weight and live weight to volume can be done by running (separate) regressions using the assumption
W = ρV or W = a + bV
