outlier.tree Hangs Indefinitely with Certain Numeric Columns Present in Dataset

[statadvice]

Hello! The outlier.tree process does not complete when running on a dataset with only numeric variables, but it finishes quickly if I remove columns 4 and 6. I haven't identified any specific characteristics in these columns that could be causing the slowdown (or even non-termination).

Keeps executing for hours and even days without terminating:

library(outliertree)
library(rio)
selected_data<-import("https://data.statadvice.com/selected_data.xlsx")
outliers_model = outliertree::outlier.tree(selected_data)

Works fast:

library(outliertree)
library(rio)
selected_data<-import("https://data.statadvice.com/selected_data.xlsx")[,-c(4,6)]
outliers_model = outliertree::outlier.tree(selected_data)

Thanks for the bug report. I unfortunately cannot access the domain data.statadvice.com and thus cannot download the file.

Would you be able to attach it here, or to upload it to some other service like dropbox?

Also a few questions:

• What kind of setup is this? (e.g. operating system, CPU architecture, etc.)
  • Are you using some platform where the type long double would correspond to 128-bit floating points? (e.g. PPC, some ARM platforms I think)
• Did you install this package from source, or did you download a pre-built version from CRAN?
• What kind of size does the data have, and what kind of values do the problematic columns have? e.g. are they all ones and zeros, non-negative numbers, very small numbers, etc.

@david-cortes Here is the data file: selected_data.xlsx OS: Windows 10, 64bit CPU: x64 (64-bit) pre-built version from cran the data is 3200 obs of 6 numeric variables found in the 174KB Excel file found above

Thanks. I was able to download the data and can reproduce the issue - will investigate.

Thanks, should be solved now. It will take a while for the update to reach CRAN, but in the meantime, the updated version can be installed from github:

remotes::install_github("david-cortes/outliertree")
