General ⇒ sorry, I have to ask this again.

I made a similar code as yesterday. It didnt work. Sorry I have to ask the similar question.
I want to let "=" be alignment points
Do I need 'split' in this case?

Code: Select all

   
\begin{align}
   
   \text{Nominal significance level:} \quad\alpha &= 0.05   \par
   \text {Target Power of the test:}  \quad \beta &= 0.80  \par
   \text{Sampling ratio: } \quad        \theta &= 1 , 1/2 \par
   \text{Assumed treatment difference:} \quad \delta &= 0.1  \par
   \text {Assumed overall event rate:} \quad \pi_{\text{asm}} &= 0.01, 0.02, 0.03,....., 0.50  \par
   \text {Actual overall event rate:} \quad  \pi_{\text{act}} &= 0.15, 0.25  \par
   \bigskip
   \text {For adaptive design, take $25\%$ of the initial sample size for the interim study: } n_{1}.=0.25n

   \end{align}

Hi,

write \\ instead of \par to end the lines.
Don't write empty lines in math environments. The text of the last line is too long.

In the other thread I already recommended some basic documentation. You can try something like the following:

Code: Select all

\documentclass{report}
\usepackage{amsmath}
\usepackage{units}

\begin{document}

\begin{align}
   &\text{Nominal significance level:}                &\alpha           &= 0.05 &&&& \\
   &\text {Target Power of the test:}                 &\beta            &= 0.80 &&&& \\
   &\text{Sampling ratio: }                               &\theta           &= 1 , \nicefrac{1}{2} &&&& \\
   &\text{Assumed treatment difference:}          &\delta           &= 0.1 &&&&& \\
   &\text {Assumed overall event rate:}              &\pi_{\text{asm}} &= 0.01, 0.02,\ldots, 0.50 &&&& \\
   &\text {Actual overall event rate:}                &\pi_{\text{act}} &= 0.15, 0.25 &&&& \\
   &\text {For adaptive design, take $25\%$ of the}   &&&&&&& \notag \\
   &\text{initial sample size for the interim study:} &n_{1} &=0.25n &&&&&
\end{align}

\end{document}

However, you could also use a tabbing environment or maybe a tabular environment. It all depends on your particular needs.

Thanks for you guys.
Have a good night!!!

I have a new question. I am use Beamer. If I want to show the formula one by one instead of showing all of the formulae at the same time, what should I do? I tried \pause, it didnt work.

Hi,

see beamer user guide 23 How To Uncover Things Piecewise and especially 23.4 Uncovering Tagged Formulas Piecewise.
