I have some data and they are expected to follow a given function. I wonder how can I find all unknown parameters in R? The function is "i = a / (t+b)^c". The objective is to find "a, b, and c". Thanks.
t = seq(from=5, to=60, by=5)
i = c(69.51, 57.55, 49.72, 44.11, 39.87, 36.52, 33.81, 31.55, 29.64, 27.99, 26.56, 25.30)
