Hi Ista, Thanks for your reply.
I had added a detailed explanation on this one & researched before asking.
May be someone did not read it i cant do much though David's explanation
helped as why it wasnt able to run the syntax.
Please see trail mail: (though i have already moved ahead and taken an
alternate package to calculate IV for each var at a time):
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
and THEN this part:
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:
