In my thesis I use \linespread{1.3} to set 1.5 line space for the entire document. However, as the following screenshot shows, the two paragraphs have different line space. Is this because of the matrix there? Or is there any other reason. FYI, this is the only place I get such ugly change of line space. Is there a way to fix it, please? For example, how can I enforce the line spacing regardless of whatever else happens. Thank you!

Update:

I tried the methods in comments. They worked but not in the way I want because all parts are affected and there appeared more unpleasant white gaps. As I showed in the picture, the rest of the document looks fine. It is only that one bit looking funny. I tried to remove the matrix and it became normal after that. But I need to keep the matrix. If it helps, I paste my entire settings below.

\noindent As that graph shows, the asymptotic variance decreases more rapidly when $\xi_0$ is positive so that almost every other $ \widehat \sigma_{MOP, \alpha}$ except those whose $\alpha$ is close to $\alpha_{op}$ has larger variance. Consequently, including all possible $\alpha$'s in fact inflates the variance. {\em These observations suggest that superficially using all data points is not necessarily the best way to utilise all the information contained in a sample. It might well be possible that using data in the wrong way can actually make things worse.}

\noindent The previous discussion prompts our suggestion of only picking a few, say, three, equally spaced percentiles which are approximately centred at the $\alpha_{op}$ as listed in Table~\ref{table: 3alphas}. We can consider this an adaptive method in which we pick different $\alpha$-triples depending on the value of $\xi_0$. To see how this works, first note that for given $\alpha_1, \alpha_2$ and $\alpha_3$, the corresponding sample percentiles $\left( x_{\alpha_1N :N}, x_{\alpha_2N :N}, x_{\alpha_3N :N} \right)^T$ asymptotically follow a three-dimensional normal distribution with mean vector $\left( x_{\alpha_1}, x_{\alpha_2}, x_{\alpha_3} \right)^T$ and variance-covariance matrix $\bm\Sigma_{\alpha_1, \alpha_2, \alpha_3}$ equal to
{\footnotesize
\begin{align*}
\frac{\sigma^2}{N}
\begin{bmatrix}
\alpha_1(1-\alpha_1)^{2\xi_0-1}                    & \alpha_1(1-\alpha_1)^{\xi_0-1}(1-\alpha_2)^{\xi_0} & \alpha_1(1-\alpha_1)^{\xi_0-1}(1-\alpha_3)^{\xi_0} \\[5pt]
\alpha_1(1-\alpha_1)^{\xi_0-1}(1-\alpha_2)^{\xi_0} & \alpha_2(1-\alpha_2)^{2\xi_0-1}                    & \alpha_2(1-\alpha_2)^{\xi_0-1}(1-\alpha_3)^{\xi_0} \\[5pt]
\alpha_1(1-\alpha_1)^{\xi_0-1}(1-\alpha_3)^{\xi_0} & \alpha_2(1-\alpha_2)^{\xi_0-1}(1-\alpha_3)^{\xi_0} & \alpha_3(1-\alpha_3)^{2\xi_0-1}
\end{bmatrix}.

    Have you tried any other method of line streching such as \usepackage{setspace} and \setstretch{1.5} instead ? – HcN Oct 30 '15 at 2:53

    Better to use the setspace package. It at least takes some basic precautions. On the other hand, for all we know, you're using an incompatible class, a class which does its own thing or not using LaTeX at all. I mean, really, how are we supposed to guess at the problem just from seeing the output? – cfr Oct 30 '15 at 2:54

    \linespread{<factor>} is functionally equal to \renewcommand\baselinestretch{<factor>}; both take effect only when followed by \selectfont. I assume something in the code is "resetting" things (you'd be surprised how often some of these commands get called behind the scenes), but it is hard to say when we don't have any code to look at.... – jon Oct 30 '15 at 3:53
  • may be linespacing is set bigger inside remark environment. – touhami Oct 30 '15 at 5:53
  • @jon I have added my full settings to the question. – LaTeXFan Oct 30 '15 at 5:57

tex does not apply the \baselineskip until a paragraph is completed. a math display does not automatically end a paragraph, and since you have used \footnotesize for the display, even though that is inside a local group and does not persist beyond the display, it still applies to the "unfinished" paragraph that precedes it.

to repair this, you will need to end the paragraph before the display. i suggest doing this as follows:

... equal to%
\par\nobreak
\vspace{-\abovedisplayskip}
{\footnotesize
 \begin{align*}
...

the % at the end of the text is to avoid a space that, if the line is close to the full page width, could (if you have very bad luck) result in an extra blank line. \par is self-explanatory. \nobreak is an attempt to keep the display from splitting to a new page. and the reversal of the \abovedisplayskip is to avoid the extra space that isn't needed since your baselines are already expanded.
