Dear list, I have to vectors:
x <- rep(c(2,4,8,24,48,72),2) y <-c(82543,169105,207615,96633,31988,7005,82687,172931,205541,101842,31898,69 50) that follows a log-normal function as f(x)= SO/(sqrt(2*pi)*sigma *x) * exp(-(ln x - mu)^2/(2*sigma^2)) that is a log-normal distribution multiplied with SO. How can I estimate SO, mu and sigma in R ?
