主题：葫芦僧乱判葫芦案 -- 煮酒正熟

So I may not be able to discuss statistics in detail. But I have general trust in our folks in the Advanced Analytics team. I have no problem at all with your challenging on statistical analysis method. The thing is, you don't yet know the bolts and nuts in our industry and our company, it's very likely that your challenge is just not valid. I have no doubt that you can always come up with great insights in your own research area, with the combination of an excellent knowledge about your subject and a solid understanding in statistics. Yet without the specific knowledge in another industry and research area and equipped only with statistics knowledge, it's likely to fall when making a challenge or judgment.
