Importing the CRISP data into the `winner' database (Amir)
Data file is located in: E:\McNair\Projects\Winner's Curse\Data\CRSP-Oct10-c30cc89e52b70545-1.txt
Issue 1: The text file is 8 GB large and there's no way to open it in Textpad. I'll try to read the file in LogExpert which seems to do a neat job in in opening large files. Otherwise, I'll try to read the first few lines in the terminal. Update: I managed to open the file in LogExpert. However, extremely inefficient to scroll over the file.
I copied the file to Z:\WinnersCurse\CRSP-oct10
Entered the following command in the terminal to read the header: head -1 CRSP-oct10.txt
