The letters in various fonts often have specific, fixed meanings in particular areas of mathematics.
Greek letters (e.g. θ, β) are commonly used to denote unknown parameters (population parameters). [3]A tilde (~) denotes "has the probability distribution of". Placing a hat, or caret (also known as a circumflex), over a true parameter denotes an estimator of it, e.g., ^ is an estimator for .
For consistency with the LaTeX style, do not italicize capital Greek letters; e.g. n! = Γ(n + 1) .
