I am trying to produce a contour plot for a likelihood profile,
using ImplicitPlot. The two dimensional fuction I am trying to
contour involves minimizing with respect to two other nuisance
variables. As a simplified example, consider
f1[x1_,x2_,x3_,x4_] :=
(x1-1)^2 + (x2-2)^2 + (x3-3)^2 + (x4-4)^2
f2[x1_,x2_] :=
Module[
{x3,x4},
FindMinimum[f1[x1,x2,x3,x4],{x3,0},{x4,0}][[1]]
]
ImplicitPlot[f2[x1,x2]==1,{x1,0,2}]
When I do this, I get a string of errors and no plot. Can anyone
help? Thanks.
I am running MMA 3.0 on a Power Macintosh 9500/200, System 7.5.5.
