我操, 最怕猪头张中国数盲说数学。
统计学里有门time series analysis,啥都不管,就管时间为X对Y影响。股票市场90%分析属于time series analysis。
所有数据都有定义,如果定义1970年为起点,猪头张问那么1970年以前呢???定义变没完没了???
世界上没有完美model,能搞定time series猪头张你发达了。

回复 8号:What is used in this article is not Time Series Analysis, just simple linear regression, but used in an incorrect way.
The author of this article is a mathematical dumb abusing the mathematical modeling, he doesn't have any math knowledge, all he does is applying model randomly and interpret the results in his way.
