I'm somewhat a novice in writing letters in LaTeX, and I would like to shy away from the standard Times New Roman font. Specifically, I would like to use Raleway font, but I have no idea how to implement this. I've researched, but can't find anything.
[Tex/LaTex] How to change the font to Raleway in letter class

First select the package that changes the math font and the text font, such as
\usepackage{mathpazo}
And then change the text font.
\renewcommand\rmdefault{hpv}% or whatever
Addressing your questions in turn:
To change only the math-mode font, while leaving the text-mode font unchanged (cmr, right?), you could load either the
newtxmathpackage or themtpro2(short for MathTime Professional II) package. (Note that the latter package isn't free; however, a subset of the fonts, called the "lite" set, provides basic lettering capabilities -- but not "fancy" math fonts such as fraktur, caligraphic, curly, and blackboard bold styles -- and is free.) Themtpro2font features "optically sized" glyphs for first-level sub- and superscript materials (aka "scriptstyle"-level materials).- Separately, if you happen to use LuaTeX or XeTeX, you may want to give the "XITS Math" font package a try.
- If you happen to be a font purist: be aware that these font packages technically give you Times Roman, not Times New Roman. And if you're not a font purist? You may be excused for not noticing any differences -- they are are quite subtle.
In math-mode, be careful about making some symbols both bold and italics. In mathematics, each font shape and weight is generally understood to impart some special meaning. For sure, do not combine bolding and italics just for emphasis. Both
newtxmathandmtpro2provide methods for changing the slant of both lowercase and uppercase greek letters.To make all displayed equations be set flush-left rather than centered, use the document class option
fleqn.How to set the contents of equations more compactly? Aaah, some would opine that MS Word's math mode is far too compact, leading to frequent overlaps of letters on the baseline and those in superscript or subscript position. Good news for you: Both
newtxmathandmtpro2render math expressions more compactly than does TeX's default math font (Computer Modern).
Putting these things together and simplifying some of your math code along the way leads to the following modified form of your MWE. The main substantive changes I've made are to replace the equation environment with an align environment and to replace the inner split environment with a bmatrix environment.
\documentclass[fleqn]{article}
\usepackage{amsmath}
\newcommand\QSJ{\mathit{QSJ}} % define a couple of acronyms
\newcommand\CML{\mathit{CML}}
\usepackage{newtxtext,newtxmath}
\begin{document}
\begin{equation}
\begin{split}
L_{\CML}( \theta )
&= \Biggl(\, \prod_{g = 1}^{\QSJ - 1}
\prod_{g' = g + 1}^{\QSJ}
P\left( [ y ]_g = [ m ]_g,\ [ y ]_{g'} = [ m ]_{g'} \right)
\Biggr)\\
&= \Biggl(\, \prod_{g = 1}^{\QSJ - 1}
\prod_{g' = g + 1}^{\QSJ}
\begin{bmatrix}
\phantom{-}\Phi_2 ({\tilde \vartheta }_g,{\tilde \vartheta }_{g'},\nu_{gg'})
- \Phi_2 ({\tilde \vartheta }_g,{\tilde \phi }_{g'},\nu _{gg'})\\
- \Phi_2 ({\tilde \phi }_g,{\tilde \vartheta }_{g'},\nu _{gg'})
+ \Phi_2 ({\tilde \phi }_g,{\tilde \phi }_{g'},\nu _{gg'})
\end{bmatrix} \Biggr)
\end{split}
\end{equation}
\end{document}
For comparison, here's how the equations look like if the times (for text font) and mtpro2 (for math font) packages instead of the newtxtext and newtxmath packages. The overall look is very similar, but the output produced with help of the newtxmath package is a bit more compact.

You need the raleway-package on your system. If you don't have a complete LaTeX-installation – in which case you don't have to do anything – you can use the package manager of your distribution to install the package.
Then you can just use the raleway font by putting
\usepackage{raleway}in your preamble. Like this:Et voilà:
