similar to: analysing a three level reponse

I am analyzing a dataset on the effects of six pesticides on population growth rate of a predatory mite. The response variable is the population growth rate of the mite (ranges from negative to positive) and the exploratory variable is a categorical variable (treatment). The experiment was blocked in time (3 blocks / replicates per block) and it is unbalanced - at least 1 replicate per block. I am

Dear all I need to obtain an estimate of the 50% lethal dose (LD50) from a logistic regression model obtained by applying the glm procedure to some binomial data. The model appears to fit the data very well. I used dope.p from MASS to try and find LD50. The following output appears: > dose.p(iso.glm.logit, cf = c(1,3), p = 1:3/4) Error in dose.p(iso.glm.logit, cf = c(1, 3), p = 1:3/4) :

Does anyone know how to extract residuals in lmer? Here's the error I get: > crop.lme=lmer(response~variety*irrigation*pesticide+(1|rep)+(1|rep: pesticide)+(1|rep:pesticide:irrigation), crop.data) > qqnorm(crop.lme) Error in qqnorm.default(crop.lme) : y is empty or has only NAs > resid(crop.lme) NULL Thanks! --Jake

Hi, we internally are creating gems out of particular sets of models, both to share them among multiple Rails apps, but also to use them within background scripts. If possible, I''d like for the models to function with ActiveRecord/ ActiveSupport as the only dependencies and not require a full Rails environment. This is for the purposes of our background jobs which use the same set of

Yes, more dependencies.rb fun! As far as I''m able to ascertain, these errors started appearing after upgrading from Rails 2.3.1 to 2.3.2 and persist in 2.3.3. They''re highly nonderministic and appear rather sporadically, which makes it extremely frustrating. Multiple developers on our team have experienced this problem across varying versions of Ruby/Rails. They''re

Whilst debugging a problem in dovecot LDA over the last few days, I came across two different issues in coding techniques. (Note: Please don't take this negatively; my intent is both positive and constructive!) The front page of the website www.dovecot.org says: "it uses several coding techniques to avoid most of the common pitfalls" So I hope it is OK to follow the spirit of

I am analyzing a dataset on the effects of six pesticides on population growth rate of a predatory mite. The response variable is the population growth rate of the mite expressed as ln(Nfinal/Nstarting) of the mite, where N final the population of the mite at the end of the experiment and N starting the population of the mite at the beginning of the experiment. Each of the six treatments was ran

Respected Sir/Madam, I have a question regarding calculation of LD50 (Lethal Dose) and IC50 (50% inhibitory concentration) of an antimicrobial experiment. I have used a compound isolated from a plant and observed its effect on the fungus *Fusarium oxysporum* by the food poisoning method. Solutions of the compound at concentrations of 0, 50, 100, 150, 200 and 250µg/ ml were added to

Good morning, I wrote a little code in R which has to show two graphs but I can get only one. How can I adress the graphs in two files? Second, I'd like, always in the same code, to add a legend to a graph. Better, I'd like to put in such a legend a new item whose color could remind the colour ol the columns it refers to in the plot. I wrote: leg.txt<-c("control

Hi, I'm new to CART. I have a data set with a binary reponse (0/1) and several predictors. I chose 2 continuous predictors to start and used the following code. testdata.ltr<-tree(nondev85dev06~dist_rampm_wa + dis_prim_wa,testdata) The two predictors should be quite explanatory based upon previous work. After running this code, I am getting only one split using the first predictor

Dear R friends- I'm attempting to generate a regression tree with one gradient predictor and multiple responses, trying to test if change in size (turtle.data$Clength) acts as a single predictor of ten multiple diet taxa abundances (prey.data) Neither rpart or mvpart seem to allow me to do multiple responses.

This is not a request for help, but I thought the readers of this mailing list might appreciate the following, anyway. I have been working with US EPA's (that's the United States Environmental Protection Agency) Office of Pesticides on a preliminary assessment for the effects of exposure to multiple organophosphate pesticides on human health (as required by the Food Quality Protection

Aside from the replay attacks discussed, there are some other attack vectors on the cookie_session store. I appreciate (and admire!)
