想要理清我的方程式

Question

我想改善方程部分的外观。长回归方程目前很高/堆叠，我认为如果将它们水平拉伸一点，它们可能会看起来更好。此外，我的第三个方程从技术上讲不是一个方程，而是一个句子（当你看到它时你就会明白我的意思）。你能看看吗？

我的 MWE：

\newcolumntype{L}{>{\raggedright\arraybackslash}X}

\newcommand\mC[1]{\multicolumn{1}{C@{}}{#1}} % handy shortcut macro

\sisetup{group-separator={,}, group-minimum-digits=4}
\usepackage[skip=1ex]{caption}
\captionsetup[table]{font=small, labelfont=bf, singlelinecheck=no}

OLS Regression is used to estimate the following equations:

目前的情况如下：

非常感谢您的帮助！

Answer 1

首先，你永远不应该用公式结束一个段落\\，也不应该在显示的公式前留一个空行

\ \ 
\\

在方程产生最大不良程度的输出之前

Underfull \hbox (badness 10000) in paragraph at lines 45--47

方程式中主要的视觉错误在于第一行在 = 的右边，但也不能用于array方程式（它是为数组/矩阵设计的，并且设置了 textstyle 中的单元格，不显示样式，并且间距错误），请使用 ams 对齐

你实际上不应该有连续的显示数学（我这里有连续的多行）但现在已经很晚了，也许这会让你更接近，我只是在这里用一个负的 vskip 进行了补偿。
