Dear User R It's been a pleasure talking with you. I am newcomer use R. Would you please help me how to translate the script below to "R" script? * Area under receiver operating characteristic (AU-ROC) predict r1m1p, p roctab malaria r1m1p, graph summary * Area under receiver operating characteristic (AU-ROC) curve predict r1m2p, mu roctab malaria r1m2p, graph summary ************************************************************ ******************** * FIGURE 1 - AU-ROC *********************************************************...

This is a bit obscure but caused me some grief... R1.5.1/MS Windows There seems to be a peculiarity in legend associated with the use of expression text. It seems as if expression text is used in (eg) an mtext call then if the call to legend also includes expression text and a subscript then the legend box and line spacing depends on the value of cex used in the previous call to mtext,

I took into consideration the steps provided by Grueber et al (2011) Multimodel inference in ecology and evolution: challenges and solutions in JEB. I created a global model to see if malaria prevalence (binomial distribution) is related to any life history traits of 14 different birds species, while controling for Family and genus in a GLMM: global.model.Para<-lmer(cbind(Parahaemoproteus,FailPh)~factor(SS)+factor(NT)+NH+W+IT+factor(MS)+(1|Family/Genus),family=binomial,data=malaria)...

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-tre...

...xed models. Since that time, has anyone written or found R code to use a glmm to analyze binomial data? I study CWD in white-tailed deer, and I'd like to do a similar analysis as Kleinschmidt et al. (2001, Am. J. Epidemiology 153: 1213-1221) used to assess control for spatial structure in malaria incidence in South Africa. They used SAS PROC MIXED in an iterative procedure with a poisson model, although due to widely varying sample sizes I'd prefer to treat my data as binomial (e.g., CWD pos or neg rather than number of CWD pos deer).

Hi, I am trying to run a logistic regression to look at the risk of malaria infection in individuals. I want to account for intra household correlation and so want to include a household level random effect.
