we are trying to analyze if family firms perform better than non-family firms. Thus we have a dependent variable of ROA and an independent dummy variable (0=non family, 1= family firm).
We want to do a regression model, but don't understand the outcome of the regression. If the dummy variable has a standardized beta of 0.2 for example, does this mean that whether or not a firm is a family firm, has a positive relationship on firm performance? or how do we realise a standardized beta for family firm on firm performance (ROA), and a standardized beta for non-family firms on firm performance? So we can compare and see which type performs better?
