Introducing LaTex

To write mathematical notation, we will use LaTex, a documentation software specifically for technical writing. We can write equations in two ways:

Inline: Your mathematics will display within the line of text.

Use $ to start and end your LaTex syntax.
Example: The R Markdown text The null hypothesis is $H_0:\beta_1 = 0$ is rendered as "The null hypothesis is $H_0:\beta_1 = 0$

Displayed: Your mathematics will display outside the line of text

Use $$ to start and end your LaTex syntax. Example: The R Markdown text The null hypothesis is $$H_0:\beta_1 = 0$$ is rendered as "The null hypothesis is \[H_0: \beta_1 = 0\]

One way we will use LaTex is to write model equations:

\[Y = \beta_0 + \beta_1 X + \epsilon\]

Syntax: $$Y = \beta_0 + \beta_1 X + \epsilon$$

Note: You cannot copy and paste mathematical symbols in LaTex. If you do so, you will get a “Unicode” error message when you try to knit the document.

See Mathematics in R Markdown for an overview of the syntax for commonly used equations and symbols.
