UK DATA ARCHIVE DOCUMENTATION

4607 - Home OnLine, 1998-2001



Data Archive processing standards
---------------------------------

B

The data were processed to the UK Data Archive's 'B' standard. A 
substantial series of checks was carried out to ensure the quality of 
the data and documentation. Firstly, checks were made that the number of 
cases and variables matched the depositor's records. Secondly, logical 
checks were performed on a sample of 30 +10% of the remaining nominal 
(categorical) variables had values within the range defined (either by 
value labels or in the depositor's documentation). Thirdly, any data or 
documentation that breached confidentiality rules were altered or 
suppressed to preserve anonymity.

All notable and/or outstanding problems discovered are detailed under 
the 'Data and documentation problems' heading below.



Conversion of data and documentation formats
--------------------------------------------

The data were received as SPSS .sav files and converted to SPSS portable files.


Data and documentation problems
-------------------------------

In the datafiles adyslots.por, bdyslots.por, and cdyslots.por, the variables 
represent the following data:

variables l to de : original alphanumeric variable labels for the diary part
of the HoL data. These diary data contain variables for every quarter hour
of the day, which comes to 96 variables.

var1 to var 96 : the numeric version of the above 

apr1 to apr96 : primary activities in quarter-hour slots (bpr1, cpri1)

ase1 to ase96 : secondary activities in quarter-hour slots (bse1, cse1)

apno : person number in household in wave 1, this is an identifier which
enables matching to the other wave-1 files.



The values 8 and 9 for the categorical variables are often not labelled. They 
should be 8= Don't know, 9= Refused.
