Unable to render formula
This latex is correct
$$
\underbrace{E[Y_i|D_i=1]- E[Y_i|D_i=0]}_\text{Observed difference in average health} =
\underbrace{E[Y_{1i}|D_i=1]- E[Y_{0i}|D_i=1]}_\text{Average treatment effect on the treated} +
\underbrace{E[Y_{0i}|D_i=1]- E[Y_{0i}|D_i=0]}_\text{Selection Bias}
$$
Yet to make it work here in github, I must escape _\ to \_\
$$
\underbrace{E[Y_i|D_i=1]- E[Y_i|D_i=0]}\_\text{Observed difference in average health} =
\underbrace{E[Y_{1i}|D_i=1]- E[Y_{0i}|D_i=1]}\_\text{Average treatment effect on the treated} +
\underbrace{E[Y_{0i}|D_i=1]- E[Y_{0i}|D_i=0]}\_\text{Selection Bias}
$$
After escaping the underscores it does work $$ \underbrace{E[Y_i|D_i=1]- E[Y_i|D_i=0]}_\text{Observed difference in average health} = \underbrace{E[Y_{1i}|D_i=1]- E[Y_{0i}|D_i=1]}_\text{Average treatment effect on the treated} + \underbrace{E[Y_{0i}|_i=1]- E[_{0i}|_i=0]}_\text{Selection Bias} $$
Any idea if this can be resolved as it appears to be similar in root cause to the issue when trying to render this
$$
\begin{aligned}
Y_i &= \left \{
\begin{array}{ll}
Y_{1i} & \text{if } D_i = 1 \\
Y_{0i} & \text{if } D_i = 0 \\
\end{array}
\right. \\
&= Y_{0i} + (Y_{1i} - Y_{0i})D_{i*}
\end{aligned}
$$
Resulting in this error
$$
\begin{aligned}
Y_i &= \left {
\begin{array}{ll}
Y_{1i} & \text{if } D_i = 1 \
Y_{0i} & \text{if } D_i = 0 \
\end{array}
\right. \
&= Y_{0i} + (Y_{1i} - Y_{0i})D_{i*}
\end{aligned}
$$
Change the latex like this
$$
\begin{align}
Y_i &= \left \\{
\begin{array}{ll}
Y_{1i} & \text{if } D_i = 1 \\\\
Y_{0i} & \text{if } D_i = 0 \\\\
\end{array}
\right. \\\\
&= Y_{0i} + (Y_{1i} - Y_{0i})D_{i*}
\end{align}
$$
Amending the original \{ to \\{ and the \\ to \\\\ resolves the issue
$$ \begin{align} Y_i &= \left \{ \begin{array}{ll} Y_{1i} & \text{if } D_i = 1 \\ Y_{0i} & \text{if } D_i = 0 \\ \end{array} \right. \\ &= Y_{0i} + (Y_{1i} - Y_{0i})D_{i*} \end{align} $$
Mathjax correctly renders the latex and I can extract it for use elsewhere.
With thanks
