Code Linear Linear regression Regression

AI Thread Summary

Recommendations for a weighted linear regression code in Fortran 90/77 or C are sought after, specifically for processing a three-column file. Simfit is mentioned as a potential resource, though it may not directly cater to the specific file format requested. The emphasis is on finding a concise routine rather than a comprehensive solution.

Hi Guys,

Can anyone recommend a code, preferably in fortran 90/77, or possibly in C, which provides a weighted linear regression of a 3 column file?

There will be routines in Simfit to do it (not sure specifically about a 3 column file): http://simfit.silverfrost.com/

Hmm thanks but I'm really looking for a short routine in Fortran or C.

Thread 'Learning Assembly and computer architecture for x86'

Dear Peeps I have posted a few questions about programing on this sectio of the PF forum. I want to ask you veterans how you folks learn program in assembly and about computer architecture for the x86 family. In addition to finish learning C, I am also reading the book From bits to Gates to C and Beyond. In the book, it uses the mini LC3 assembly language. I also have books on assembly programming and computer architecture. The few famous ones i have are Computer Organization and...

Thread 'Microsoft Technical Interview question'

I had a Microsoft Technical interview this past Friday, the question I was asked was this : How do you find the middle value for a dataset that is too big to fit in RAM? I was not able to figure this out during the interview, but I have been look in this all weekend and I read something online that said it can be done at O(N) using something called the counting sort histogram algorithm ( I did not learn that in my advanced data structures and algorithms class). I have watched some youtube...
