Inquiry Regarding "Not Given" Values in Impression Section of Test Sets ¶
By: Sunggu on July 11, 2025, 7:06 a.m.
Hello, While conducting exploratory data analysis (EDA), I noticed that the "impression" section is sometimes marked as "Not Given" and treated as a null value. I would like to ask whether such "Not Given" entries also exist in the impression section of the internal or external test sets.
Thank you in advance for your clarification.
