Question

求教目前在cocos2dx 2.2.2中怎么使用cocostudio

Answer 1

Q2 for the extracted components.
Q2(cum) is computed as:
(1.0-π（PRESS/SS）a)

(PRESS/SS)a = the product of PRESS/SS for each individual component a.
When a component is insignificant we truncate the value PRESS /SS for that component to –0.1, when that value is smaller than
–0.1
where SS is the residual sum of squares of the previous component,
所以我又迷惑了，这个simca-p算出来的Q²还是预测值和真实值之间的相关系数么~~

Answer 2

只是版本不同，功能基本相同。
