Dear Stata Community,
I am rather new to Stata and try to incorporate it into my empirical study on crypto-currency forking. In my analysis, I intend to use the eventstudy2 package by Thomas Kaspereit. My analysis actually includes 126 events. However, I am confused because the number of events (from the 126) changes with each iteration of running the code because I think the number of events that the command is able to incorporate in the analysis should be constant (an example is depicted below):
Example Iteration 1:
Example Iteration 2:
To obtain this result I used the following command:
Data frame containing the events
Data Frame containing returns (Table name: Indicators)
Thank you very much in advance and kindest regards,
Niklas
I am rather new to Stata and try to incorporate it into my empirical study on crypto-currency forking. In my analysis, I intend to use the eventstudy2 package by Thomas Kaspereit.

However, I am confused because the number of events (from the 126) changes with each iteration of running the code because I think the number of events that the command is able to incorporate in the analysis should be constant (an example is depicted below):
Example Iteration 1:
Code:
Number of events in the event file: 126 -- thereof: Number of events for which security identifiers and event dates are available: 126 -- thereof: Number of events for which event dates are in the range of dates in the security file: 126 -- thereof: Number of events in the analysis (not deleted because of any insufficient data in the estimation or event period): 105 List of security identifiers for which no security market data was available: ANALYSIS OF ESTIMATION PERIOD Number of events with insufficient security return data: 0 ANALYSIS OF EVENT PERIOD Number of events with insufficient security return data: 0 Events for which the IPO (deletion) date of the event firm is later (earlier) than the first (last) day of the event window: 21
Code:
Number of events in the event file: 126 -- thereof: Number of events for which security identifiers and event dates are available: 126 -- thereof: Number of events for which event dates are in the range of dates in the security file: 126 -- thereof: Number of events in the analysis (not deleted because of any insufficient data in the estimation or event period): 88 List of security identifiers for which no security market data was available: ANALYSIS OF ESTIMATION PERIOD Number of events with insufficient security return data: 0 ANALYSIS OF EVENT PERIOD Number of events with insufficient security return data: 0 Events for which the IPO (deletion) date of the event firm is later (earlier) than the first (last) day of the event window: 38
To obtain this result I used the following command:
Code:
eventstudy2 fork_id date using Indicators, returns(ret) model(COMEAN) evwlb(-30) evwub(30) eswlb(-200) eswub(-31) car1LB(-20) car1UB(20) car2LB(-10) car2UB(10) car3LB(0) car3UB(5) car4LB(0) car4UB(10) parallel replace
