Hi all,
I have a function like the following:
f <- function(r,
y){r/(2*pi)*exp(1)^(-y)*(1+r*(y/2)+r^(2)*(y-1)^(2)/6)}
For fixed r, I want to find the inverse funtion in terms y.
In other words, for fixed r, if the value of the function is given, I want
to
find the corrsponding y value that will achieve the specific function value.
Can anyone help me?
