I need the parameters estimated for a non-linear equation, an example of the
data is below.


rm(list=ls())
Time<-c( 0, 0, 0, 0, 0, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 4, 4, 4,
4, 4, 5, 5, 5, 5, 5, 8, 8, 8, 8, 8)
Level<-c( 100, 110,  90,  95,  87,  60,  65,  61,  55,  57,  40,  41,  50,
47,
44,  44,  42,  38,  40, 37,  37,  35,  40,  34,  32,  20,  22,  25,  27,
29)
plot(Time,Level,pch=16)
