Title

Using Quality of Government (QoG) data

Syntax

qoguse
[varlist]
[if] [in]
,
version()
format()
[years()
clear]

Description

The QoG-data is a dataset containing aggregate statistics of the quality of government of
various countries worldwide measured at various points in time. It is provided by
University of Gothenburg: The Quality of Government Institute.

qoguse loades the most recent release of the Quality of Government (QoG) datasets from the
internet into memory. If you don`t need the complete dataset, you can opt for specific variables with [varlist]
and/or years with the option years.

Options

version() defines which version of the QoG-data you want to use. The alternatives are Basic (bas), Standard (std), OECD (oecd),
Expert Survey (exp), EQI (eqi) and EU Regional (eureg). Each version has different formats which you have to specify:

format() defines the different datasets. For the Basic, Standard and OECD version you can choose between Cross-Section Data (cs) and Time-Series Data
(ts). For the Expert Survey and EQI data you can choose individual (ind) or aggregate (agg) formats. The EU Regional data is available in three formats:
Long (long), NUTS 1 (wide1) and NUTS 2 (wide2).

other Options

years(numlist) specifies the different years to be kept in the data. You can use a numlist
to specify the years, which must be in 4-digit-format (e.g. years(1990 1995/1997 2002)).
This option is only available with format()-options: ts, long, wide1, wide2 and for EQI data with format(ind).

clear specifies that it is okay to replace the data in memory,
even though the current data have not been saved to disk.
