Not our problem.  Please correspond with the maintainer of that package.

Hi David,

If this has loaded correctly then it still does not allow me to run
iv.multi command where a can add all the variables in the model and
find
their respective WOE and IV values.

Thanks, Shivi

HI Team,

I am working to reduce the # of predictor variables from the model

using

woe and iv values. For this i am using riv package. However i am

having a

hard time installing this package:

install_github("riv","tomasgreif")
install.packages("DBI",dependencies=TRUE)

The error i receive is :
*Username parameter is deprecated. Please use tomasgreif/riv *

No. You did not get an error message. It was clearly labeled a

:Warning

message". Here is the full console output from that call:

install_github("riv","tomasgreif")

It's just telling you to use this next time:

install_github("tomasgreif/riv")

I will lay long odds that you already have the package installed.

I cannot comment on what this package purports to do. I'm somewhat
suspicious that it is statistically suspect.

David.

The other approach i have to use the library(InformationValue). I

have

this

as below:
WOE(X=SFDC1$support_cat, Y=SFDC1$survey)
WOETable(X=SFDC1$support_cat, Y=SFDC1$survey)
IV(X=SFDC1$support_cat, Y=SFDC1$survey)

This package assists me achieve what i am looking for but here i

need to

add one independent variable at a time to see whether it is

predictive or

not. Is there a way i can add all variables at a go or have to add

one by

one,

For the above package (riv) i have seen an example which helps to

take

the

entire data range and  predictive the power of each predictor. The

link

for

the same is:
