Re: Specifying weight in R2MLwiN

Hi, I have a similar problem before. However, the problem was solved after I upgraded the MLwiN to version 3.02 and installed R2MLwiN using

Code: Select all

library(devtools)
install_github("rforge/r2mlwin", subdir="R2MLwiN")

Re: Using predict() to calculate predicted value

Do you mean in this case I need to manually add 4 columns of Intercept into the data frame?

Thanks,

Re: Using predict() to calculate predicted value

Hi Chris, Thanks for your quick reply. I replicate the example from http://www.bristol.ac.uk/cmm/media/r2mlwin/MCMCGuide13.R . data(alevchem, package = "R2MLwiN") alevchem$gcseav <- double2singlePrecision(alevchem$gcse_tot/alevchem$gcse_no - 6) model1 <- runMLwiN(a_point ~ 1 + gcseav + I(gcseav^2) +...

Using predict() to calculate predicted value

Hi, I'm following the suggestion from this post https://www.cmm.bristol.ac.uk/forum/viewtopic.php?f=7&t=2010&p=4572&hilit=predict&sid=a398d4a33ea73179434b8589781fa976#p4572 to replicate the standardised residual vs predicted value within R. I am two models. Model 1 is a 2-level random slope model wi...

Fail to store residual for cross-classified model

Hi, I am running a cross-classified cumulative logit model for my ordinal outcome. I used the following codes to store the residual: estoptions = list(resi.store = TRUE, resi.store.levs = c(2, 3, 4), xc = TRUE, EstM = 1 However, I have this error: Error: memory exhausted (limit reached?) In this cas...

Predicted Probability for cross-classified ML model

Hi, I would like to calculate the population-averaged probability for a cross-classified ML model. I have read this post: https://www.cmm.bristol.ac.uk/forum/viewtopic.php?f=3&t=1558&p=3867&hilit=predicted+probability&sid=16e1ae467bd040ff6cbae53ea3c523fb#p3867 , 2. Depends on whether you want cluste...

Re: Level 2 residuals for ML cumulative logit model

Hi, I'm using data (9.1wsz) from Module 9. The data is converted to dta and then imported to R. The categorical variable (occtype) is converted into dummy variables. Here is the syntax for replicating the random slope model: data9.1$occtype0 <- dummy.code(data9.1$occtype) RSmodel <- runMLwiN(logit(e...
