search for: lsqlin

...nitial guess x0 must be in the fasiable region and NOT in the boundaries (due to trick I only have boundary), this trick doens't work out. If constrOptim doesn't make subject to equalities, what function could do this optimization ? any ideia ? I look for something similar to MATLAB's lsqlin function: http://web.media.mit.edu/~bill/workspace/matlab/toolbox/optim/lsqlin.html

Is there a function in R for constrained linear least squares? I used the matlab function LSQLIN: my aim is to obtain non-negative regression coefficients which sum 1. Thanks in advance, domenico vistocco ___________________________________ Yahoo! Mail: gratis 1GB per i messaggi e allegati da 10MB http://mail.yahoo.it

Hi, Anybody knows how I can go about solving a linear least square problem with bounds? In Matlab I can use lsqlin but I haven't been able to get anything in R.
