About my multiple linear regression solver

[Ramine]

Hello,


The multiple linear regression solver is inside the "test.pas" example
inside the zipfile..

Please note that the example inside the "test.pas" have a mathematical
function of 4 variables as:

a5:=f(a1,a2,a3,a4)


but notice that if you are using a mathematical function of 4 variables
as in my example inside
the test.pas source code, the 5th variable inside the mat2 matrix must
be always 1,
this is how my solver works, but i you have a mathmatical function of 2
variables the 3th variable inside
the mat2 matrix must be always 1 , please take a look at the source code
inside
the "test.pas" example and you will understand , it's really easy to
work with my multiple linear regression solver.

And since i am using an optimized LU factorization method that uses SSE2
instructions to compute the inverse matrix, this will give a more
numerically stable method to compute the inverse. Cause LU factorization
is a more numerically stable method, read here:

Hello again...


If you want to compile my multiple linear regression solver inside the
"test.pas" source code with Delphi XE versions , just open the test.pas
source code and change the:

"uses LinMath,sysutils,math;"

to

"uses LinMath,system.sysutils,system.math;"



That's all,
Amine Moulay Ramdane.
