I can't seem to center equations without causing some weird formatting problem. The following results in the R being dropped:
\begin{center}
E(R_{i,t})=E(\alpha_i)+E(\beta_{i,F_1 } F_{1,t})+E(\beta_{i,F_2 } F_{2,t})+\ldots+E(\beta_{i,F_m } F_{m,t})\linebreak
\bar{R}_{i,t}=a+\hat{\beta}_{i,F_1 } E(F_{1,t})+\hat{\beta}_{i,F_2 } E(F_{2,t})+\ldots+\hat{\beta}_{i,F_m } E(F_{m,t})\linebreak
\bar{R}_{i,t}=a+\gamma_1\hat{\beta}_{i,F_1 } +\gamma_2\hat{\beta}_{i,F_2 } F_{2,t}+\ldots+\gamma_m\hat{\beta}_{i,F_m }
\end{center}
Any ideas? Is {center} the wrong thing to use?
Best Answer
For a series of centered equations use the
gather
environment of amsmath:Instead of centering you may consider to align all equations at the equal sign and center the whole multiline environment. For this, use the
align
oralign*
environment, see the amsmath user's guide (or type texdoc amsldoc at the command prompt).In any case, use
amsmath
. That package provides many kinds of multiline diplayed formula environments.
