How we can solve this problem: error in db choice: Error in optim(ini, fn = dbLL, method = "BFGS", hessian = TRUE, dvar = yvar, : initial value in 'vmmin' is not finite In addition: Warning message: glm.fit: algorithm did not converge

Error in optim(ini, fn = dbLL, method = "BFGS", hessian = TRUE, dvar = yvar, :
initial value in 'vmmin' is not finite
In addition: Warning message:
glm.fit: algorithm did not converge

I think we need to see your code and some sample data. See
FAQ Asking Questions

A handy way to supply some sample data is the dput() function. In the case of a large dataset something like dput(head(mydata, 100)) should supply the data we need. Just do dput(mydata) where mydata is your data. Copy the output and paste it here between
```

```

Thank you so much. Here is code, output problem and data used for analysis; I will appreciate if you can suggest for solving this problem

Code: install.packages("Icens")
install.packages("DCchoice")
install.packages("aods3")

library(aods3)
library(Icens)
library(DCchoice)

cvm_data1 <- read.table("my63sampledatacsv.csv",sep=",",header=T)

모델 ì í•©

model1 <- asw1 + asw2 ~ 1 | log(bid1) + log(bid2)
model1_result <- dbchoice(model1, data = cvm_data1, dist = "log-logistic", maxit=1000)

Result Problem:

At the moment I cannot install {Icens} or {DCchoice} and apparently {Icens} ism no longer on CRAN but available on Bioconductor so I am not sure how much I can help.

I hope someone with a familiarity with Bioconductor can help. If not I'll see what I can do but it's outside my area.
