Replace missing values based on another attributes
I am new to Rapidminer and i have a question regarding data preparation. It looks a bit like this question, but i can't figure out how to apply this to my situation.
I have a dataset regarding accidents, and this datset contains the following attributes:
Total Fatal Injuries Total Serious Injuries Total Minor Injuries Total Uninjured
Missing Missing Missing 1
Missing Missing 2 Missing
2 2 Missing Missing
1 Missing Missing Missing
Missing Missing Missing Missing
I would like to fill in the missing values with ''0'' only if one of the four attributes contains a value.
I am not very experience with RapidMiner, and I'm learning through a book called ''Data Mining for the Masses''. Unfortunately, the book won't go into detail in these kind of problems.
I already tried to use the Generate attributes operater with the following code, but I am not skilled enough to get it to work:
if([ Total Uninjured ]>0, if(missing([ Total Fatal Injuries ])), then(replace(0)))
I tried to tell the program that if ''Total Uninjured'' is greater than ''0'' and ''Total Fatal Injuries'' is missing, replace ''Total Fatal Injuries'' with 0.
Any help would be greatly appreciated!
