Case Study: The Spanish Wine Industry
Results
The
\(R^2\) values, or the adjusted coefficient of regression, are different for
each of the three studies and they vary from 0.260 for cooperatives (\(n =
42\)), the lowest value, to 0.435 for individual wineries (\(n = 37\)), and
0.462 for mercantile wineries (\(n=159\)). These values were also found in
other comparable studies, for example, 0.390; 0.279, and suggest that the model provides
sufficient information to draw conclusions.
