This is a Markdown document.
It's easy to do italics or make things bold.
All models are wrong, but some are useful. An approximate answer to the right problem is worth a good deal more than an exact answer to an approximate problem. Absolute certainty is a privilege of uneducated minds-and fanatics. It is, for scientific folk, an unattainable ideal. What you do every day matters more than what you do once in a while. We cannot expect anyone to know anything we didn't teach them ourselves. Enthusiasm is a form of social courage.
Code block below. Just affects formatting here but we'll get to R Markdown for the real fun soon!
x <- 3 * 4
I can haz equations. Inline equations, such as … the average is computed as \(\frac{1}{n} \sum_{i=1}^{n} x_{i}\). Or display equations like this:
\[ \begin{equation*} |x|= \begin{cases} x & \text{if $x≥0$,} \\ -x &\text{if $x\le 0$.} \end{cases} \end{equation*} \]
