BUS602: Marketing Management

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.
