Dear Statalist members,
I am using a dataset from the WRDS database. I have annual data for my firm (gvkey)
i would like to ask: It's possible to merge these two files as "fundamental" contains 471 variables and 38921 observations, but "daily security" contain 12 variables and 13947724 observations. It does not merge due to the different number of observations.
When I want to merge annual fundamental data and daily security data with this code:
Merge 1:m gvkey year month using security daily. doing this, I always receive the following error code:
Can somebody help?
Thanky you in advance
