Dear R-helpers, I'd like to understand how to test the statistical significance of a random effect in gamm. I am using gamm because I want to test a model with an AR(1) error structure, and it is my understanding neither gam nor gamm4 will do the latter. The data set includes nine short interrupted time series (single case designs in education, sometimes called N-of-1 trials in medicine)

Simon, in your recent reply to me, you noted that EDF=1 corresponds to a straight line fit. Does the edf always indicate the polynomial exponent directly? We ask because Hothorn and Everitt said "Roughly, the complexity of a cubic spline is about the same as a polynomial of degree one less than the degrees of freedom." Sorry we attributed the latter to you, by the way. Will --

Hi, ? I'm trying to carry out Cramer von Mises tests between pairs of vectors belonging to a discrete distribution (concretely frequencies from 0 to 200). However, the program crashes in the attempt. The problem seems to be that these vectors only have positive integer numbers (+ zero). When I add a random very small positive decimal to the non-decimal part everything works fine (files prm1

Dear R-Helpers, I posted two days ago on testing significance of random effects in mgcv, but realize I did not make my overall purpose clear. I have a series of N short time series, where N might range from 3-10 and short means a median of 20 time points. The sample data below (PCP) has N = 4 cases with 9, 13, 16 and 16 observations over time respectively. The data set contains four

Hall all, Where can I find the two sample Cramer-von Mises test in R package? Thank you. Legendy -- View this message in context: http://www.nabble.com/Two-sample-Cramer-von-Mises-test-tp20174229p20174229.html Sent from the R help mailing list archive at Nabble.com.

We are using GAM in mgcv (Wood), relatively new users, and wonder if anyone can advise us on a problem we are encountering as we analyze many short time series datasets. For each dataset, we have four models, each with intercept, predictor x (trend), z (treatment), and int (interaction between x and z). Our models are Model 1: gama1.1 <- gam(y~x+z+int, family=quasipoisson) ##no smooths Model

Hello, Please let me know how I can troubleshoot this - driving me crazy!

I received the warning "DNS updated failed!" during net join. Is this an important warning? Will there be problems? Immediately after the join, clients using smbclient were able to authenticate and access shares on this server - even though "net ads testjoin" complained about kerberos problems. # net join -U Administrator Administrator's password: Using short domain name

Dear R-helpers, I was testing the truncgof CRAN package, found something that looked like a bug, and did my job: contacted the maintainer. But he did not reply, so I am resending my query here. I installed package truncgof and run the example for function ad.test. I got the following output: set.seed(123) treshold <- 10 xc <- rlnorm(100, 2, 2) # complete sample xt <- xc[xc >=

Greetings, R users! I'm excited and pleased to announce that the weightr package was released to CRAN today: https://cran.r-project.org/web/packages/weightr/ Our package provides a function for meta-analysts to implement the Vevea and Hedges (1995) weight-function model for publication bias in R and, by specifying an additional argument, to implement the modified Vevea and Woods (2005)

The report on R_help about problems loading package irr (in a UTF-8 locale, it seemed) prompted me to look a little deeper. There are quite a few packages with Latin-1 chars in their .R files, and a couple in UTF-8. Apart from non-ASCII chars in comments, this is a problem as the code concerned cannot be represented in some locales R runs in (for example Japanese on Windows). It happens

Estimados amigos, Estoy familiarizándome con los modelos lineales generalizados en R. Estoy interesado en realizar un análisis lig linear y me gustaría saber cuáles son o como extraer los valores correspondientes al chi cuadrado en el análisis para cada grupo y para las interacciones. Desde ya muchas gracias y disculpas si la pregunta es muy básica, adjunto los comandos que estoy utilizando. Si

Dear Sir I am new user of R. I am interested in modeling hydrological extreme events. I found MSClaio2008 very interesting function. In this function four criterions for choosing distributions. Can we call these criterions as model selection techniques or goodness of fit techniques or both? Because goodness of fit techniques are usually performed after modle selection. Can I found

Hello, Well... thanks to the input of all of you I have my dovecot->ldap connection working for almost all of my clients, however... on outlook, a message for certificates being trusted comes up, the user clicks yes and connection fails. Questions: Do I have to get an ssl certificate to make it work? ( cost ouch!) Is there a way around this using my own self-signed certificates? Is there

Dear all, I'm performing RDA on plant presence/absence data, constrained by geographical locations. I'd like to constrain the RDA by the "extended matrix of geographical coordinates" -ie the matrix of geographical coordinates completed by adding all terms of a cubic trend surface regression- . This is the command I use (package vegan): >rda(Helling ~

Dear R users; Is there a function in R that I can put "text" with proper alignments in a fixed format. For instance, if I have three fields: A, B and C, where both A and C are text with 3 characters and left alignment; B is a numeric one with 2 decimals and 3 integer space digits. How can I put the following row in a file? (note there is a space between a and 2, and after b.)
