latex中多行公式左对齐

要在LaTeX中实现多行公式的左对齐，你可以使用amsmath包中的flalign环境。以下是一个示例代码：

\begin{flalign}
& (a) Sparsity : \hat{\beta}_{nA^{C}}= 0 & \nonumber \\
& (b) Orthogonal : X_n^T\hat{\varepsilon}_n = 0 & \nonumber \\
& (c) Homoscedasticity : E(\hat{\varepsilon}_n^2 | X_n) = \sigma^2 & \nonumber \\
& (d) No Endogeneity : E(X_n^T\hat{\varepsilon} | X_n) = 0 & \nonumber
\end{flalign}

在这个示例中，每行公式都被对齐到左边，并且不带有公式编号。使用\nonumber命令可以阻止对特定行进行编号。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
