Assunto: Re: [R] How to do log normal regression?
1. Have you considered nls or optim? The documentation for both
includes useful examples.
2. What do your Y values

2. What do your Y values represent? The almost universal standard
today is maximum likelihood estimation. If you tell us what the Y
values are, someone might help you write a

variables, and estimate the parameters. Is there any
package/functions designed for this purpose?
Basically, I have data for Y and X, and I suspect the
relationship between Y and X is Y = CDF Log-Normal
(X), and I want to run this regression
