Hi,

\n

I thought that it was not allowed that RV/LV-gte and RV/LV-lte both equal zero? Because there are rows in the train.csv file where both RV/LV-gte and RV/LV-lte are both equal to zero. I thought this was impossible? How can the ratio be neither greater than or equal to 1 and less than 1 at the same time?

\n

Thanks,
\nJay

It is only for studies that are positive for pulmonary embolism. For negative studies it is not filed in and if I understand correctly, is not scored. Same for left, right, central and acute, chronic.

Thank you Richard. If a study is found to be indeterminate, are right/left/center/acute/acute+chronic and RV/LV ratio also calculated?

I believe not. Based on the flowchart at the end of the competition's data description page, if an example is either indeterminate or negative then all of the above should be 0.

I think they are mutually exclusive. Can you provide an example where they are not?

Actually I believe Richard's comment below is more precise.
