发帖数: 4 | 1 I have a basic question, thank for help very much.
I have 2 pc connected by a hub, then connect outside by
cable.
I want file sharing between the 2 pc, how to do that?
1. I install network neighbour,
2. check the "file and printer sharing" in the control
pandel>>network,
3. 2 pc have the same group name in the control

"file and printer sharing of MS network"
oh btw, now my network properties are:
Microsoft cl |

match,
都不知道为啥会要我去面。。。
securities strats:
(1) 经典random walk的问题 1出发回到0或到达3停止，到达3的概率，以及停止时间的
期望。
(2) Bt是Brownian motion, Xt = 2^Bt, 问Xt是否是martingale，如果不是，如何做
change of measure把Xt变成martingale.
(3) 给3个currencies的exchange rates, 如何找arbitrage, 推广到n个的case, 算法
复杂度.
qis:
(1) bs的assumption都有啥，和efficient market hyothesis的关系
(2) cross-sectional time series analysis 和pandel data analysi之间的关系
(3) linear regression的assumption
(4) name trading strategies you knew
(5) cap... 阅读全帖 |

牛。急求，愿意付报酬。SAS例如：
proc model data=tempdone;
instruments a b c d e f;
X=h0+h1*Y+h2*Z+h3*taadj+h4*leverage+h5*a+h6*b;
Y=g0+g1*X+g2*Z+g3*taadj+g4*leverage+g5*c+g6*d;
Z=b0+b1*Y+b2*X+b3*taadj+b4*leverage+b5*e+b6*f;
fit X Y Z/ no2sls gmm vdata=vblkdiag vardef=n nogengmmv;
但这个应该是对cross sectional的，有大牛能指点下如何做pandel data的吗？有
module或者codes吗？ 还有一点，其中X是0，1变量； Y，Z是非连续数，如1，2，3...
..23(是个ordinal的数）。 |
