解释:
老师好,我有三个小问题:
1、decimal form,还是那个问题。如果看到题目中写“decimal form” 是不是就不用管什么百分数或者小数,正常把每一个数按照我们中国人的思维来计算就好了啊?
2、offer size 的t统计量很小,要忽略这一项吗?怎么判别是否忽略?
3、最后的fraction retained 这一项,我理解是IPO时自己留下的份额,这个在中文里的术语叫啥来着?

NO.PZ2015120204000013 0.1064. 0.1541. C is correct. The precteinitireturn (IR) is: IR = 0.0477 + (0.0150 × 6) + (0.435 × 0.04) – (0.0009 × 40) + (0.05 × 0.70) = 0.1541同上,关于对t检验的考量,当题中出现这个条件
NO.PZ2015120204000013 如上请问题目中的40m,为什么就用40来算,而不是40000000
NO.PZ2015120204000013 算法我理解为什么答案是0.1541啊,这个式子算出来不是0.1384吗
所以上面说的一堆公式其实没啥用?我看了半天???
