As shown in picture, that's what I want.

Very close but no good enough

[casperyc]

Code: Select all

\documentclass{article}
\usepackage{multirow,bigdelim}
\usepackage{blkarray}

\begin{document}



\[
	\begin{blockarray}{[c]c}
		p_2 & \rdelim\}{3}{0pt}[$K-1$]\\
		\vdots \\
		p_K \\
		\tau_2 & \rdelim\}{3}{0pt}[$K-2$]\\
		\vdots \\
		\tau_{K-1} \\
		-
		\left\{
			\mu
			+
			\sum\limits_{c=2}^C w_c\eta_c
		\right\} & \rdelim\}{1}{0pt}[$1$] \\
		w_1 \mu^2 
		+
		\sum\limits_{c=2}^C
		w_c(\mu+\eta_c)^2 & \rdelim\}{3}{0pt}[$K-2$]\\
		\vdots \\
		w_1 \mu^{K-1}
		+
		\sum\limits_{c=2}^C
		w_c(\mu+\eta_c)^{K-1}
	\end{blockarray}
\]


\end{document}

Look pretty much it.

But is there a way to "automatically" adjust the last two " \rdelim\}" to the same height as its neighboring content?

Many thanks,
