verifying some ideas. Details then can be done with more sophisticated model.
A microwave model is easy, it's linearly proprotional to temperature

hoho, just kidding.
,TMI, VIRS, AMSR-E, CERES, 发现拿来做用户名挺好的,大多时候没被人用过,呵呵

remember the area is proprotional to cos(lat)
This is why from 30S to 30N, the area is half of the total spherical
area.
Afica has a big chunk in tropics, while North American is really
further polarward a lot. |

W**********E 发帖数: 242 | 4 如何SIMULATE SURVIVAL TIME 并能按预定比例CENSOR(25%,50%,75%)?
比方说TIME TO DEATH ~EXPONENTIAL DIST(RATE=XXX),然后CENSORING TIME~
UNIFORM(0,C)。如何确定这个C最后的数据有预定的CENSORING PROPORTION(25
%,50%,75%)?
谁有这方面的经验
THANKS, |

then censoring rate is Pr(C |
