I am importing a csv file (attached) of time series numeric data which contains occasional missing values as ".."
The simple import code I am using is:
Code: Select all
import M:\ExportDirect.csv colhead=1 @freq Q 1986q1- HLFQ_SMB1JCA
HLFQ_SMB2JBE
HLFQ_SMB3JBF
HLFQ_SMB3JCK
Any suggestions as to how I can get the import to recognise the ".." as missing values?
I tried the following, but it did not work:
Code: Select all
import M:\ExportDirect.csv na=".." colhead=1 @freq Q 1986q1
