习惯上都是以e为底,但我弄成以10为底了
理论上说我觉得没什么错
但就是怕审文的人挑理
我用不用改回去?

回帖推荐for some data, the return, firt difference of log price, is usually
very small, at round second decimal. You can computer without
multiplying 100, however, the precision will be affected.
You can imagine when you evalute the residual, how small it is.
When you multiply by 100, you can raise your precision while get the consistent coefficient parameters.
