NOMOGRAM with 4 variables - HELP !!!
For determination of a medical index I "designed" the following equation ÃÂ ( x,y,z,p ) = 0:
x - p +y(z-x)/10x + 3 = 0
0<x<5 0<y<20 xÃÂ¾z<15 x+3ÃÂ¾p<15
and would now like to graphically describe its solutions in form of a nomogram. The literature I searched only stated nomograms with three variables, for n-dimensional functions it didnÃÂ´t give any useful advice.
I appreciate very much any response regarding references to 4-dimensional nomograms or advices how these can be created. Maybe someone knows of a program which "just plots out" the nomogram, honestly, I would like that best ! ThankÃÂ´s !
