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.
