Hello, I have a what I believe is a really simple question. I don't work in SAS very often, and am trying to use it to gain more comfort with basic functions I am trying to plot a Von Bertalanffy growth equation Lt=Linf*(1-exp(-k*(age-t0))) where Lt is length at age t. I am working with fish, and want to use this plot to find what length they would be expected to be at age 1-20. The parameters for the equation are Linf=900, k=0.15, t0=-0.99 Below is my failed attempt at plotting the equation. Clearly I'm off base. I'd appreciate help in getting it to plot, and finding lengths at age. Thank you! Data VonBert; Input Linf k t0; datalines; 900 0.15 -0.99 ; run; proc plot data=VonBert; plot Linf*(1-exp(-k*(age-t0))); run;
