find_shift_values {PhylogeneticEM} | R Documentation |
Find values given edges. OU stationary case. Ultrametric tree.
Description
find_actualized_shift_values
computes the values of the shifts their
positions, and the mean values at the tips.
Warning : this function does not check for consistency. Please make sure that the
shifts positions and the mean values are compatible.
Usage
find_shift_values(shifts_edges, T_tree_ac, vect_Y, p, ntaxa)
Arguments
shifts_edges |
a vector of positions of shifts on the tree. |
T_tree_ac |
matrix of incidence of the tree, result of function
|
Details
This function uses qr.solve
for rectangular linear system solving.
Value
vector, with first entry the values at the root, and other entries the values of the shifts.
