WebDec 9, 2024 · I'm calculating the weights of 10 securities in a portfolio for a course project, with the objective of maximizing the sharpe ratio. I'm getting both positive and negative results for weights. The course guide says that negative weights mean that the optimal portfolio contemplates short selling. The results looks like the image.

WebOct 3, 2012 · library (glmnet) loReg <- glmnet (x=X, y=Y, family = "binomial", lower.limits = 0, lambda = 0, standardize=TRUE) The above line will create a logistic model with penalizing coefficient equal to zero (which is what you want). Since the lower limit of all of your variables is the same (i.e. zero), setting lower.limits=0 will do the job. WebJul 9, 2024 · Teams. Q&A for work.
