similar to: comparison of parameters for nonlinear regression

Hi, I'm trying to make a regression of the form : formula <- y ~ Asym_inf + Asym_sup * ( (1 / (1 + (n1 * (exp( (tmid1-x) / scal1) )^(1/n1) ) ) ) - (1 / (1 + (n2 * (exp( (tmid2-x) / scal2) )^(1/n2) ) ) ) ) which is a sum of the generalized logistic model proposed by richards. with data such as these: x <- c(88,113,128,143,157,172,184,198,210,226,240,249,263,284,302,340) y <-

Motivated by the discovery of 'loglet analysis' (http://phe.rockefeller.edu/LogletLab/) that allows one to decompose growth curves into a series of logistic equations, I attempted to do the same thing in R. SIMULATED DATA Time <- 1:200 pop.size <- SSlogis(Time,10,20,5) + SSlogis(Time,20,100,20) + rnorm(length(Time)) MY ANALYSIS results <- nls(size ~ SSlogis(Time, Asym1, xmid1,

Dear list, Apologies, I have sent this message before but received no replies so I'm trying again just in case...

To whom it may concern I made some analysis with R using the command Anova. However, I found some problmes with the output obtained by selecting type II o type III sum of squares. Briefly, I have to do a 2x3 mixed model anova, wherein the first factor is a between factor and the second factor is a within factor. I use the command Anova in the list below, because I want to obtain also the sum

Any idea what might be wrong?

Hello there! Yesterday I started my experiments with HTB. I configured it this way: 1: root HTB qdisc | 1:1 HTB class rate 1000kbit | /-------+------\ 1:40 1:50 1:60 user1 user2 user3 rate 333 & ceil 1000 for everyone. User2 is disconnected and user1 and user3 are downloading. For all the time (t1-t5) there are ONLY these two users downloading! HTB should give

My students are working with several SPSS dataset provided by the European Social Survey. If you register your name, you can download it too. This is the 2004 data, for example: http://ess.nsd.uib.no/ess/round2/ I cannot give you the European Survey dataset, but you can download it for free if you like, and then you could run these commands to re-produce this weird pattern described below.

I just did a clean install of Fedora 9 onto a Pentium 4 machine. It is actually running SELinux enforcing, but I haven't found any errors related to that so far. It is running Samba 3.2.3-0.20. I am trying to migrate a Windows NT 4.0 domain with about 30 users and 30 computers onto a pure Samba setup, using Samba as the PDC and tdbsam. I have read the HOWTO guide extensively, and

wondering if anybody knows this......does shady dial work only with a zap interface or can it be configured to be used with SIP or IAX.

Hi, During tests with a IAX2/PSTN gateway I've been getting strange results for processor idle time and load. I (re)search(ed) this issue for a while, but I didn't get any good explainations. Can somebody help me? I have several sites that rely on a central server for connection to the PSTN. Calls to the PSTN are routed over the Internet to this PSTN gateway using IAX2 in trunk mode. To

Heya.. Yesterday someone "attacked" by box by connection to several ports.. In other words, a simple portscan.. yet, since my box has "log_in_vain" enabled, so it tries to log everything to /var/log/messages, since the logfile got full and the size went over 100K, it tried to rotate the log to save diskspace.
