Notes on the Nor98.sav file:

Nor98.sav is an SPSS datafile containing estimates of the positions of the major Norwegian political parties on ten issues and a left-right ideological scale, as well as estimates of the salience of each of these dimensions for each of the Norwgian parties. These data were obtained through an expert survey of Norwegian political scientists conducted in 1998 at the Norwegian Academy of Science and Letters.

For a description of the expert survey used to produce these estimates, as well as an analysis of them see the following publication: Leonard Ray and Hanne Marthe Narud, 2000. "Mapping the Norwegian Political Space: Some Findings from an Expert Survey," _Party Politics_ 6: 225-239.
