I have the following data in R
x <- c(0.1,0.2,0.3,0.6,0.8,0.9,1) y <- c(90,96,97.7,99.3,99.65,99.95,100)
I'm trying to find a logarithmic equation that best fits these points. I'm not sure what the equation would look like, but probably something like one of these
What kind of curve do you think best fits this data. And how can I find out?
