Dear Team, can i use MarkowitzModel to solve the weights for solving 50 X 50 variance covariance matrix & 1X50 return matrix (i.e 50 variables) ? plz. note that i'll also setting up the expected return to some const. value. i have tried with 4 X4 matrix (setting up the expected to some const. value) & it worked perfectly fine, amzingly fast & accurate. in this case i'll need 50 setupper limit & 50 set lowerlimits will ojalgo support caculation of such large model. also wanted to know the wt. is the max. possible value of n matrix (n X n) [i.e n variable]supported by ojAlgo MarkowitzModel ? and any advice for solving large number of variables with this model? Thanks & Regards....Nilesh |
