Shivi, Looking at the help from ?WOE, ?WOETable, and ?IV, your Y vector in all cases is to be categorical and it is numeric. Mark R.

These are the packages i am using: library(woe) #WEIGHT OF EVIDENCE library(InformationValue) #INFORMATION VALUE The syntax used is : WOE(X=SFDC1$log_caseage, Y=SFDC1$survey) WOETable(X=SFDC1$case_age, Y=SFDC1$survey) IV(X=SFDC1$case_age, Y=SFDC1$survey) On Wed, Aug 31, 2016 at 12:54 AM, Mark Sharp <msharp at txbiomed.org>

Shivi, What package(s) are you using. What functions are you using. How are you
calling the functions. A reproducible sample has all of the actual code needed to create a representative error. There are multiple packages you could be using to look at weight of evidence and information value. For example, there is a WOE function in the Information package and a woe function in the woe package.

significant variables that is where i get this error. Thanks for your assistance Mark really appreciate i will look into some other measure on this.

Shivi, It is likely that William knows what you are trying to do because of
his considerable experience, but I am not able to figure it out from what you have written. You have apparently sent the output from something like dput(SFDC[1:50, ]), but I still do not know what you did to get the error.
I successfully assigned the structure you sent to the name SFDC and
nothing seems amiss.
