Description
Table 7. On the basis of linear regression analysis followed by post hoc likelihood ratio test, the diameter of umbilicus is mostly dependent on the diameter of the shell and can be best modelled as the linear expression of diameter of the shell and the height of whorl. It is least dependent on the thickness of the whorl, especially when modelled alongside the diameter of the shell.
