Ques-7: In order to improve all of three models simultaneously, we can remove variables which are not significant in any of the above models. In the given case, variables LEV and CLTR can be removed as they are not statistically significant in any of the models and would not impact the explanatory power of the models much.
Moreover, variables Leverage and current liabilities don’t have any impact on EBIDTA and hence, removing them won’t have any negative impact on explanatory power of 3rd model.
Ques-7:为了提高所有三个模型的同时,我们可以删除变量不显著的高于模型。在给定的情况下,可以删除变量列弗和CLTR因为它们不是统计学意义的模型和不会影响模型的解释力。
此外,利用变量和流动负债对营业,因此没有任何影响,移除它们不会有任何负面影响3号模型的解释力。
