I want to create a dummy variable redundism which
equals dummy = 1 if the establishment has had any
dismissals or redundancies in the past 12 months. I
would be grateful, if anyone would let me know if the
following is the correct way to do it. There is a
debate amongst us at whether it in the second line it
should be "|" or "&". I would be grateful, if you
would confirm if the following is correct or should it
be an "&"
ge redundism=.
replace redundism=1 if zredundab==1|zdismissa==1
replace redundism=0 if zredundab==0|zdismissa==0
-----------------------------------------------------------
By your description it is an OR, i.e. "�". However,
the sequence of the two -replace- commands is wrong.
Now it gives this result:
. input zredundab zdismissa
zredundab zdismissa
1. 0 0
2. 0 1
3. 1 0
4. 1 1
5. end
. ge redundism=.
(4 missing values generated)
. replace redundism=1 if zredundab==1|zdismissa==1
(3 real changes made)
. replace redundism=0 if zredundab==0|zdismissa==0
(3 real changes made)
. list
+--------------------------------+
| zredun~b zdismi~a redund~m |
|--------------------------------|
1. | 0 0 0 |
2. | 0 1 0 |
3. | 1 0 0 |
4. | 1 1 1 |
+--------------------------------+
Try swithching the two -replace- commands.
Hope this helps
