Roadmap
The total sample size is 708.
These are the households from 1997 dataset
with data on the business.
Out of 708 cases
Followed in 2000
N=553
99 closed /
33 still open but
with a different BM
In 2000
 421 Still involved in the same open business
(without complete information).
 325 business managers still managing same open
business (with complete information).
 311 cases where complete info & bus still open and
managed by same BM and has HM info
 Difference between 325 and 311 is that there are
14 BM only data included in 325.
The final syntax file to be used

Filter to get to n of 325 BM still managing same open
business with complete information.
 Coms9700>=1& Coms9700<=4

 & Openbu00=1 (Bus still open)
 & Manbs00=1 (Business Manager or Household Manager Still

Answer
 It describes the positive stress index for 311
Businesses in 2000 where business is still open and
managed by the same business managers with
complete information and has Household Manager
information as well.
 Try using N=325 and using a HM variable(e.g.,
Hzb1b00) . You should get 14 missing! That’s
because: Difference between 325 and 311 is that
there are 14 BM only data included in 325.
Homework Assignment
 1. Get frequencies for businesses
followed in 2000 from n of 708 in 1997. Find
the total frequencies for the variable
‘whether business comes first’? How many
answered ‘yes’ and how many ‘no’?
Answer to Qs.1
 Use filter to get N=? ;
 Use the filter to get N=533;
 Use ? variable to get total frequencies?
 Use variable busfirst00 to get total
frequencies
 N = ?, ‘Yes’=? and ‘No’ = ?
 N = 553, ‘Yes’=135 and ‘No’ = 418.
Qs.2. Get frequencies for the variable ‘negative
stress index’ for cases where business is still
open, managed by same BM and with
complete information in 2000.
Answer to Qs.2
 Use filter to get ? cases?
 Use filter to get 325 cases.
 Use ? variable to get the frequencies?
 Use variable nstress00 to get the frequencies.
 N=?, missing =? Value Categories ?
 N=325, missing =0. Value Categories
0,1,2,3.
