Dear Clyde Schechter and other Stata experts,
I have the raw data as follows:
Th
Here is my results,
I guess that the problem is when I post the raw data, I choose the firms randomly, which is located at column IM and IP. So, Mr Clyde though I have only 2 firms. Actually, I have over 1000 fims, which is from column B to ADE.
I look forward to hearing from you.
I have the raw data as follows:

e raw date is exported from Datastream in a form of row, the first column is Date, the sencond column is stock price of firm 1, the thirst column is for firm 2 and so on.....
I need to format the raw data. In details, I need to transpose the panel data to the form that all firms are in one column, and then the next column is Date. But I do not know how to do. Could you please help?
Mr @Cylde gave me the code in previous topic like this
Mr @Cylde gave me the code in previous topic like this
rename A str_date
foreach v of varlist IM-IP {
rename `v' price_`=strtoname(`v'[1])'
}
drop in 1
destring price_*, replace
gen date = daily(str_date, "MDY")
assert missing(date) == missing(str_date)
format date %td
drop str_date
reshape long price_, i(date) j(firm) string
rename price_ price
foreach v of varlist IM-IP {
rename `v' price_`=strtoname(`v'[1])'
}
drop in 1
destring price_*, replace
gen date = daily(str_date, "MDY")
assert missing(date) == missing(str_date)
format date %td
drop str_date
reshape long price_, i(date) j(firm) string
rename price_ price
Here is my results,
Code:
foreach v of varlist B-ADE{
2. rename `v' price_`=strtoname(`v'[1]0)'
3. }
B ambiguous abbreviation
r(111);
I look forward to hearing from you.
Thank you very much in advance.
