[Help] Error when using nls
Hi,
I am a student of Earthquake Engineering, and am new to R.
Currently I try to run nonlinear regression analysis by R. My data
has three variables: X, Y, and Z. Z is a function of (X, Y). My R
script is as below.
rm(list=ls())
# read in data
Alldata <- read.table("~/Documents/R/Wu_data.dat", header=TRUE)
# assign variables
Z <- Wu[[1]] # N1,60
X <- Wu[[2]]

[nls] singular gradient
Hi, I am new to R. I don't have strong background of statistics. I am
a student of Geotechnical Engineering. I tried to run a nonlinear
regression for a three-variable function, that is
N = f(CSR, ev) # N is a function of CSR and ev, and N = CSR/(A
+B*CSR), wherer (A,B) are function of ev.
N, CSR and ev are observed in the experiments.
Following is my R script.

why results from regression tree (rpart) are totally inconsistent with ordinary regression
Hi,
In my analysis of impacts of insecticide-treated bednets on malaria, I
look at the relationship between malaria incidence and mosquito
behaviors. The condensed data set is copied here. Ordinary regression
(lm) shows that Incidence was negatively related to Mortality. This
makes sense because the latter reflected the strength of killing
mosquitoes by insecticide-treated nets. Since the

failover for shorewall
I am using shorewall-4.2.5-1 on RHEL-5.2 for a MultiISP connection.
Everything works great. I run vpn, proxy, mail relay on the firewall.
Hence I do the application level management.
So far I was using third party script "gwping" for my failover
mechanism. Just wondering if shorewall has any native programs to handle
fail over ?
Thank you
