发帖数: 11 | 6 FPKM受到library size影響，已經被淘汰了，現在都用TPM. 差異分析應該要用raw
counts. 大部份的包裹像Deseq2都用negative binominal 模型去做差異分析，
normalized之後模型就不適用了
：打车问个问题，RNA-seq做差异分析的时候，用FPKM的话，不同个体总FPKM差异非常大
：（所有基因加和10000，有的50000），于是考虑用 TPM，可否？谢谢 |

发帖数: 21830 | 7 gasuss 是因为binominal测量产生的，BW是 natural width, 因为你测量的粒子有mass.你这个fitting应该是Gaussian+BW, 根据你的detector的resolution确定Gaussian参量，根据mass确定BW参量。
难道量子场论都没学过？ |

sure BS and BT prices are always consistent given BT of N steps?
这个怎么回答 只要 N 足够大就可以了吗？ |

发帖数: 536 | 11 Sorry, I was wrong. For the binominal tree, the bigger strike is less risky.
The reason is as follows: Using the actual probability you can find that
the bigger strike has bigger actual rate of return, where all the actual
rate of return are using the absolute value. After assuming the vanishing
bank interest rate, you can show that the actual return rate equals is
propotional to the valotility. Thus we get the initial statement.

发帖数: 71 | 14 多谢大家回帖，我针对我之前没有说清楚的地方进行了一点补充。
面试官很Nice，一步步引导我啊，可惜我还是不知道如何解。。又悲剧了一个phone
interview啊。下面是两道新鲜出炉的面试题，请教大家
1.针对同一个data set,现有两个model A,B,可能是用不同的方法做出来的，DV是一样的，IV没说。 已知outcome(A)=100,outcome(B)=80, var(A)=25,var(B)=49,并且
两个Model的error都是iid的，先要把两个model结合起来,赋不同的weight, minimize
variance.怎么弄？我当时说是不是就是求Min var（w1*A+w2*B），他说不是。我真不
知道是如何结合。而且我觉得应该是要用到error iid这个条件
2.这个简单点，但当时我已经秀逗了，完全转不了脑子了，嗨。。只能怪经验太少以求
安慰了
具体我就不说了，反正我得到最后的一步就是binominal, (20,n)*(0.15)^n*(0.85)^(
20-n)=0.12,求n.那个（20，n）就是20 choose n，我不知道怎么答。这个... 阅读全帖 |
