search for: constains

I am fittting a linner regression with constrained parameters, saying, all parameters are non-negative and sum up to 1. I have searched historical R-help and found that this can be done by solve.QP from the quadprog package. I need to assess the significance of the coefficient estimates, but there is no standard error of the coefficient estimates in the output. So I can not compute the p-value.

Hi, I've just installed xulrunner-devel from yum, but there are following header files cannot be found in xulrunner-sdk-1.9/sdk/include: mozilla-config.h mozilla-config32.h prtypes.h The include/xulrunner-sdk-1.9 constains those above header files, I did link to them, but xulrunner-sdk-1.9/system_wrappers/prtypes.h has a problem as well: #pragma GCC system_header #pragma GCC visibility push(default) #include_next <prtypes.h> #pragma GCC visibility pop At final, I could not compile VLC plugin with the xulrunne...

Hi all, I am trying to estimate few parameters using the constained maximum likelihood in R and more specifically the constOptim() from the stata package in R. I am programming in Python and using R via the RPy2. In my model, I am assuming that the data follow the Beta-distribution, so I created a simulated dataset by using prespecified values for the parameters and now I am trying to estimate

Hello Everyone, My question is simply what are my best options for successfully installing virtual tools on an Open Solaris OS running on Sparc Architecture. My hardware is a Sun Blade 2500. From what I have read Virtualbox and Xen do not work on Sparc technologies. What options do I have? Thank you in advance for any advice, Dan -- This message posted from opensolaris.org

Hi, can anybody point me to a package with C++ code that call Fortran subroutines? I am trying to do the same thing but we scarce success.

I have an optimization question that I was hoping to get some suggestions on how best to go about sovling it. I would think there is probably a package that addresses this problem. This is an ordering optimzation problem. Best to describe it with a simple example. Say I have 100 "bins" each with a ball in it numbered from 1 to 100. Each bin can only hold one ball. This optimization is
