thanks...
i do homework.. my professor said , to use slover function in excel.
but i used R , so i want to find same function.
question is " Max(x,y) x*E(R.a) + y*E(R.b)" , and x+y=1,
E(R.a) and E(R.b) is average of the special data..
special data is this
-------------------------------
Nippon Steel Corp
-------------------------------
E(R) = 4.65752
V(R) = 99.05973
sqrt(V(R)) = 9.95288
-------------------------------
Chubu Electric
-------------------------------
E(R) = 2.19316
V(R) = 40.42778
sqrt(V(R)) = 6.35828
-------------------------------
TDK Corporation
-------------------------------
E(R) = 1.10754
V(R) = 24.24186
sqrt(V(R)) = 4.92360
