“按美国人的说法就是调整,按中国人的说法就是造假 ”
I discussed this with my colleague a couple of days ago, who has years of research experience in the US Census Bureau, dealing with all kinds of data. She said that she trusted the US Census Bureau. The director of the Bureau is one of her best friends and he is a candid person. Since the Bureau aims at working independently, there should not be much political impact on their data analyses.
I asked her what the possible explanation is for the revised numbers and why they were all biased in one direction. She said it was possibly because the statistical models the Bureau developed in the past might only work well in good economic conditions. So in today's market, the results were systematically biased. |
