Mean Variance Spanning test

Hi,
 
I am looking for a code for mean variance spanning test. This test was first proposed by Huberman & Kandel (1987) and recently Kan(2012) in his paper "Tests of Mean-Variance Spanning" has introduced spanning test based on GMM. 
 
Mean Variance spanning is a multivariate regression based test based on minimum variance framework. It is used to test whether adding assets to a portfolio will provide additional benefit or not. It tests the joint hypothesis of alpha = 0 and beta = 1 in the regression to test if the efficient frontier based on the original portfolio spans with the frontier of the new portfolio. If it spans then there is no benefit of adding the assets to the portfolio.
 
Please...

How to dynamically re-allocate serial buffer sizes?

I am using an RCM4100 or RCM4200 processor. For port D, for example, I know I must define the DINBUFSIZE AND DOUTBUFSIZE parameters, to say, 63 bytes. That works fine if I am using defines to alter the way the program compiles, but how do I dynamically change those values based on a DIP switch setting of my communications protocol? For example, what if I want 255 bytes for Modbus or 511 bytes for DF1 as set by a DIP switch input? Can I use malloc to change these and if so how?

Please help...

I didn't find the right solution from the Internet.

Why do programmers know more than one language?

I see that JavaScript is the most used language in the world. Why do people learn other languages, can't they write the whole application or website in JavaScript? If I want to create my own website after I've learnt the basics of computers as a whole, can't I learn JavaScript (I presume that it's the easiest language, since so many people know it) and just write the whole website in JavaScript?
 
Please Help.
Thanks !

Best Programming language for someone who is starting out?

For the past few days I've been thinking about which programming language to learn, one that is quite primitive and is easy to learn. I've decided to look at Python, Ruby, C++ (a bit advanced), PHP, C#, and Lua. 
 
 
Please Help.
Thanks !

Does anybody have an idea of a tool that can predict crime in advance?

Over the period of the past 11 months in Criminal Research, I have discovered that many events of crime occur with the assistance provided by technology. However, what I wonder is if there is a technology that prevents such crime? It would be a great help if the existence of such a tool be notified.
 
Please Help.

Didn't it come much later?

 I know it has been around for years, but I still don't get it. It's just an app where people post pictures... and nothing else. Pictures of themselves. Pictures of their drinks. Pictures of their pets... all this used to be on Facebook too, so why the switch-over?
 
Anyhow, yes, it is now clear I have been living under a rock. I'm still a geek and nerd at heart. I'm more mobile savvy than most. I play video games way more frequently than I should and spent a fortune on the dozens of gadgets/macs/PCs/Phones/Tablets and smart watch. But here is one sector of the tech industry that eluded me for the last 10 years.
 
Please Help.

"you're on instagram?

if you died at the old age of 150, and found all your relatives and friends partying in heaven and all welcoming you with open arms to the club with that "where the hell were you all this time?" kind of feeling.
 
Almost every single one of my relatives, friends, colleagues... EVERYONE was posting on it, and frequently!
 
needless to say, I feel like I have been living under a rock all this time. Sure, I heard 3rd party apps were popular among the younger generations, but I had always been assuming that amongst the older millenials... those who had been on Facebook since teenagehood... FB would still be the app to go to.
 
This feeling held true mainly because of how everyone had kept using FB Messenger...
