D.15.9.1 likeIdeal
Procedure from library maxlike.lib (see maxlike_lib).
- Usage:
- likeIdeal(I,u); ideal I, intvec u
I represents the algebraic statistical model and u is the data vector under
considerarion.
- Return:
- ideal: the likelihood ideal with respect to I and u
Example:
| | LIB "maxlike.lib";
ring r = 0,(x,y),dp;
poly pA = -10x+2y+25;
poly pC = 8x-y+25;
poly pG = 11x-2y+25;
poly pT = -9x+y+25;
intvec u = 10,14,15,10;
ideal I = pA,pC,pG,pT;
ideal L = likeIdeal(I,u); L;
==> L[1]=2744y2+13003050x-2116125y-6290625
==> L[2]=9114xy-98y2+5828550x-891375y-2833125
==> L[3]=847602x2-98y2+89716875x-12967425y-43985625
