equivalent_shifts_values computes the values of the shifts given all
thepossible allocations computed by function
equivalent_shifts_edges.
equivalent_shifts_values(phylo, eq_shifts_edges, T_tree_ac, vect_Y, p)a phylogenetic tree, class phylo.
matrix (optional) result of function
equivalent_shifts_edges.
matrix of incidence of the tree, result of function
incidence.matrix, actualized with coeficients computed by
function incidence_matrix_actualization_factors.
a list of positions and values of original shifts.
value of the original optimal value at the root.
Named list, with "shifts_values" a matrix of shifts values corresponding to the shifts positions in eq_shifts_edges; and "betas_0" a vector of corresponding root optimal values.
This function uses the linear representation of the problem. It fist compute
the mean at the tips given by the orgininal shifts positions and values, and
then uses function qr.solve
to find back the values of the shifts, givent their various positions,
and the means at the tips. Function compute_actualization_factors is
used to compute the actualization factor that multipies the shifts values at
the tips. Carefull, only work for ULTRAMETRIC trees.
