9. 预测和解释（Prediction and Interpretation）：加权回归模型可以用来进行预测，并解释自变量对因变量的影响。然而，由于权重的引入，解释回归系数时需要更加谨慎。加权回归分析提供了一种灵活的方法来处理数据中的不均匀性和异方差性，从而提高模型的准确性和可靠性。在实际应用中，选择合适的权重和方差函数对于获得有效...

In addition to its theoretical support and the simple and unit-free interpretation of its slope coefficient, this model fits the data much better than the original one in a number of ways. First, this model cannot make illogical negative predictions for sales: when the forecasts for log sales...
while a blue cell signals the negative sign of the coefficient. The best model in terms of posterior probabilities on the left includes twelve out of the 34 variables used in the analysis. These variables are also the only ones with a posterior inclusion probability above 0.5. This threshold ...
