Monotonic Optimal Binning in Consumer Credit Risk Scorecard Development
Downloaded github.com/statcompute/mob/data/accepts.rds
Tried to load it into R, got this:
> load('accepts.rds')
Error in load("accepts.rds") :
bad restore file magic number (file may be corrupted) -- no data loaded
In addition: Warning messages:
1: In readChar(con, 5L, useBytes = TRUE) :
truncating string with embedded nuls
2: file ‘accepts.rds’ has magic number 'X'
Use of save versions prior to 2 is deprecated
Is this file corrupt, or have I done something stupid??

Thank you for you nice work ! But i'm not familiar with R and those binning algorithms .
So, can you give some detail paper or other reference ?
Thank you for the shout-out to the Rborist package. Please let us know whether there are any adjustments we can make to the package in order to support your arb_bin() work.
batch_bin(df, 1) -> qtl Error in parallel::mclapply(xnames, mc.cores = parallel::detectCores(), : 'mc.cores' > 1 is not supported on Windows
There are many other parallelization capabilities running on all platforms.

Hi,
There was no facility for comments at the 10th March 2019 blog post, so I resorted to leaving the comment here.
The Tibshirani and Knight paper cited in the post as Tibshirani and Knight, 1997, is actually Tibshirani and Knight, 1999. See https://www.tandfonline.com/doi/abs/10.1080/10618600.1999.10474842
That's it!
Toodles,
