Dear R-Users, I have fitted a cross-classified generalized linear mixed model using the lmer package with the following code. Mod<-lmer(y~x+(1|a)+(1|b)+ (1|c), family=binomial) In this case, only including a covariate (x) as a fixed effect. The fitted values, using fitted(mod), correspond to the raw data nicely, and the mean of the fitted values is equal to the mean of the raw data. In

Sorry for the late reply. Thanks, Eli. That was really helpful.

Hi, I''ve a little problem using the Radio Button Tag. I use the " @prove=MODEL.column_names() " to keep attribute names of a table. After i used this code to select a attribute subsets of them : <% i=''0''%> <% for @obj in @prove %> <% @key='':key''+i%> <%= radio_button_tag (@key,@obj) %> <%

the compiler tell me it: invalid column name: INSERT INTO ago.prova_stats (cognome, nome, id, telefono) VALUES(''Medda'', ''Ivan'', :id, 70565611) where ago.prova_stats is the table used by me and that have only the columns ''cognome'',''nome'' and ''telefono''. My table hasn''t the column

OK. Separate register classes should be able

Dear all, Is it possible to extract cross-validation results from e1071's svm model? For example, the following R code shows the result from the 10 fold cross-validation. model = svm(spam ~ ., data = spam, cross = 10) summary(model) But, I could not figure out how to get to the accuracy values from the cross-validation. I looked at the svm method, but did not find any return values. Any

Hi there, I really tried hard to understand and find my own solution, but now I think I have to ask for your help. I already developed some script code for my problem but I doubt that it is correct. I have the following problem: Image you develop a logistic regression model with a binary outcome Y (0/1) with possible preditors (X1,X2,X3......). The development of the final model would be

Hi, I am trying to cross-validate a logistic regression model. I am using logistic regression model (lrm) of package Design. f <- lrm( cy ~ x1 + x2, x=TRUE, y=TRUE) val <- validate.lrm(f, method="cross", B=5) My class cy has values 0 and 1. "val" variable will give me indicators like slope and AUC. But, I also need the vector of predicted values of class variable

Hi, I'm facing a problem in llvm while porting it to a new target and I'll need some support. We have 2 kind of register, one for general purposes (i.e. arithmetic, comparisons, etc.) and the other for memory addressing. Cross copies are not allowed (no data path). We use clang 3.0 to produce assembler code. Because both registers have the same size and type (i16), I don't know

Hi, I have developed a logistic regression model in the form of (factor_1~ numeric + factor_2) and would like to perform a cross-validation or some similar form of sensitivity analysis on this model. using cv.glm() from the boot package: # dataframe from which model was built in 'z' # model is called 'm_geo.lrm' # as suggested in the man page for a binomial model: cost <-

Hi, I'm performing (blocked) 10-fold cross-validation of a several time series forecasting methods, measuring their mean squared error (MSE). I know that the MSE_cv is the average over the 10 MSEs. Is there a way to calculate the standard error as well? The usual SD/sqrt(n) formula probably doesn't apply here as the 10 observations aren't independent. Thanks, Gad -- Gad

Hi all, I have a legacy table which I cannot get to work with ActiveRecord (no ids etc). All I want is to create a class which opens a connection manually and allows me to execute some plain SQL statements. What I can''t figure out is how to either build up a connection and execute queries from a non-AR inherited class, or how to create a AR-inherited class minus all the AR magic and
