getMinError | R Documentation |
Find reasonable minimum on the sigma2_error
parameter.
getMinError(phy, tol = (.Machine$double.eps)^0.5)
phy |
a phylogenetic tree. |
tol |
the numerical tolerance |
The minimum value must be high enough so that it can be numerically
distinguished from zero.
Default to tol * h
, where h
is the total height of the tree.
If an OU is used, then this value is updated to match the transformed tree height.
