Hi, I have a pretty simple problem. Here is the code: dat1=complete(dat.mice,1) dat2=complete(dat.mice,2) dat3=complete(dat.mice,3) dat4=complete(dat.mice,4) dat5=complete(dat.mice,5) dat6=complete(dat.mice,6) dat7=complete(dat.mice,7) dat8=complete(dat.mice,8) dat9=complete(dat.mice,9) dat10=complete(dat.mice,10) dat11=complete(dat.mice,11) dat12=complete(dat.mi...

IIUC, this would be an isssue with MICE (or rather "mice"), which isn't Ole's. It could be a namespace issue, but it could also be that some start-up code is not executed if library() is bypasses (see .onAttach et al.). -pd > On 4 Oct 2017, at 17:00 , Michael Dewey <lists at dewey.myzen.co.uk> wrote: > &g...

Sorry, I was not clear enough. The reason I want to use mice::mice() rather than library(mice); mice() is that I want to call it from my own package. But the reprex works from the command line as well, straight after launching R: mice::mice(airquality) #> Error in check.method(setup, data): The following functions were not found: mice.impute.pmm, mic...

Hello, I have a data set which is similar to the following data mice <- rep(letters[1:4],10) outcome <- sample(c(0,1),length(mice),replace=T) group <- c(rep("A",length(mice)/2),rep("B",length(mice)/2)) my.data <- data.frame(mice,outcome,group) my.sort.data <- my.data[order(my.data[,1]),] I would like to test wether there is a dif...

...e experts may be able to diagnose this without extra information but I suspect you have not got the right magic in your NAMESPACE file in your package. You may need to re-read section 1.5.1 of the Writing R extensions manual.

Dear R-users, Version V2.0 of the package mice is now available on CRAN for Windows, Linux and Apple users. Multivariate Imputation by Chained Equations (MICE) is the name of software for imputing incomplete multivariate data by Fully Conditional Specifcation (FCS). MICE V1.0 appeared in the year 2000 as an S-PLUS library, and in 2001 as an R...

Hi everyone, Does anyone here has experience using MICE to impute missing value? I am having problem to pool the imputed dataset for a MANOVA test, could you give me some advice please? Here is my code: > library(mice) > grd3dat=subset(paper2,Control==1&Grade_1==3,select=c(Boy,BVCategoryT1,reclassify,meanseap_1,meandep_1,meananx_1,meanper...

Hi everyone! I have data consisting of several response variables and several explanatory variables. I wish to do a permanova on this using the vegan library and the adonis() function. However, my data had several missing values in it. In order to 'fix' this I used the mice() function from the mice library to make 5 imputations for all the missing values. To do analysis on the 5 datasets with different imputed values, the mice library includes the with.mids() function in which you can call the mice object and calculate a model for all the 5 datasets. The results from...

Saludo gente, antes que nada gracias por la ayuda que puedan aportarme, soy iniciante en R, estoy usando el paquete Mice para realizar imputaciones múltiples sobre variables en su mayoría categóricas. El problema está que cuando expresó este comando imp <- mice(dataset,method="polr",maxit=1) donde el dataset es un data.frame me tirá este error : iter imp variable 1 1 pial1a pial2 pial3a pial3b...

...thod by its resulting classification error in my training data. I have tried several approaches to replace missing values: - mean/median substitution - substitution by a value selected from the observed values of a variable - MLE in the mix package - all available methods for numerical data in the MICE package (ie. pmm, sample, mean and norm) I found that the least classification error results using mice with the "mean" option for numerical data. However, I am not sure how the "mean" multiple imputatation differs from the simple mean substitution. I tried to read some of the...

Dear R users, I am using package mice and I am getting the error " Error in if (meth[j] != "") { : argument is of length zero." I have tried using several different versions of R (even the one that will be coming out this month) to no avail. I am using RStudio as my interface with R. Also note that I had run this a...

Hi all, How can I calculate the mean from several imputed data sets with the package mice? I know you can estimate regression parameters with, for example, lm and subsequently pool those parameters to get a point estimate using functions included in mice. But if I want to calculate the mean value of a variable over my multiple imputed data sets with fit <- with(data=imp, expr=mean(y...

Hi, I am attempting to impute my data for missing values using the mice function. However everytime I run the function it freezes or lags. I have tried running it over night, and it still does not finish. I am working with 17000 observations across 32 variables. here is my code: imputed.data = mice(data, + m = 1, + diagnostics = F) Thank you in advance, Richard...

I'm trying to use either mice or norm to perform multiple imputation to fill in some missing values in my data. The data has some missing values because of a chemical detection limit (so they are left censored). I'd like to use MI because I have several variables that are highly correlated. In SAS's proc MI, there is...

I'm new to R so forgive me if this seems like a simple question: So I have table where the row titles are string variables. When I plot the data with rows along the x-axis, the data is ordered alphabetically as opposed to the order of the table. How can I preserve the row order of the table in the plot? Thanks in advance. -- View this message in context:

Hi, I'm trying to impute a large data set using mice but I keep getting this: Error in nnet.default(X, Y, w, mask = mask, size = 0, skip = TRUE, softmax = TRUE, : too many (2944) weights nnet.default uses the argument MaxNWts to set a maximum number of weights. I've tried to change nnet.default to get around this, but mice is somehow still pa...
