As shown below, the summation is visible in sublime text.
The code for the equation is
\begin{equation}\label{cepl}
L = \frac{ \displaystyle \sum\limits_{x=1}^N {T_{d}^{x} - {T_{i}^{x} }} } {N}
\end{equation}
However, in the actual file, it's not.
The output is same irrespective of \displaystyle. What am I doing wrong?

The immediate problem, i.e., the missing summation symbol, can be rectified by not loading the
newtxmathpackage. Thenewtxmathpackage is in serious conflict with the subsequently-loadedmathpazopackage.If you don't know what you're doing in terms of text and math fonts and, in particular, if you don't have to use a Palatino-type font, you could skip loading the
mathpazopackage (and thenewtxmathpackage too!). That leaves the instruction\usepackage{lmodern}in your preamble. This instruction loads theLatin Moderntext and math font family. Use it unless you really need to use some other font family. (If you were to omit the\usepackage{lmodern}instruction as well, you'd get the default font family, which is Computer Modern. Unless a document contains a lot of accented characters, most people would be hard-pressed to tell the difference between Computer Modern and Latin Modern.)If you do need to use a Palatino clone, don't load the
lmodernpackage. And, do yourself a favor and don't load the nearly-obsoletemathpazopackage. Instead, load thenewpxtextandnewpxmathpackages.As I noted in my earlier comments, there are a whole host of other, nearly equally serious, deficiencies with the preamble of your document. Sooner or later -- probably sooner! -- these deficiencies are going to cause further problems. Do fix these deficiencies, and do take the time to learn the basics of LaTeX and to figure out what various packages actually do. Loading a jumble of packages (maybe in the vain hope of "covering all the bases"?) is not innocuous. Instead, it's asking for trouble and, at the very least, lots of wasted time while you track down the causes of various cryptic error messages.
