Automatization of non-linear regression
Hi everybody,
I'm using the method described here to make a linear regression:
http://www.apsnet.org/education/advancedplantpath/topics/Rmodules/Doc1/05_Nonlinear_regression.html
> ## Input the data that include the variables time, plant ID, and severity
> time <- c(seq(0,10),seq(0,10),seq(0,10))
> plant <- c(rep(1,11),rep(2,11),rep(3,11))
>
> ## Severity

different slope estimates depending on the initial break points. The results
are listed below and I'd like to know what is a reasonable approach handling
this kinds of problem. I think applying various initial break points is
certainly not a efficient approach. Is there any other methods to deal with

RES: OpenSSH with slow login
I gueess it is not a DNS problem, because either using name or IP, I have
always the problem.
I guess the problem is that I am using ssh on inetd.conf (sshd -i), so It
has to generate a key each time I start a session. What do you think ?
