Decrease vertical space between align environment and text content in RMarkdown

I am writing rmarkdown pdf documents with equations (using mac, knitr, pdf-latex). The problem I have is that rmarkdown is automatically creating a large blank gap of 2-3 lines between the preceding text and the equation. How do I get rid of this gap?

Sample rmarkdown doc below.

title: "No More Gaps"
author: "Llew Mills"
date: "16th of September 2016"
output: pdf_document
- \setlength{\mathindent}{0pt}
linestretch: 1.3
toc: yes
classoption: fleqn

Some text to illustrate the gap. I still want there to be a decent line spacing between lines of text, but I would like a much smaller gap between the equations and the preceding text.
Y_{ij} &= \pi_{0i} + \pi_{1i}TIME_{ij} + \pi_{2i}(0) + \varepsilon_{ij}\\
&= \pi_{0i} + \pi_{1i}TIME_{ij} + \varepsilon_{ij}

Can anyone help with this problem?

There are two options here. The first is just to use \vspace as I pointed out in my comment. The second one is to use \abovedisplayskip. For details on how this (and the sibling commands) works, I can refer you to Remove vertical space around align.
