What does the tilde symbol mean in statistics?
the distribution
In statistics, the tilde is frequently used to mean “has the distribution (of),” for instance, means “the stochastic (random) variable has the distribution (the standard normal distribution). If and are stochastic variables then means ” has the same distribution as .
What does a dot mean in functions?
f(⋅) Center-dot notation in functions Some papers will use a center dot (or interpunct) to represent that any value can be inserted as the value of a function. For example, argmaxf(⋅) max f ( ⋅ ) means the same as argmaxxf(x) See Mathematics StackExchange for more information.
Does a tilde mean approximately?
This symbol (in US English) informally means “approximately”, “about”, or “around”, such as “~30 minutes before”, meaning “approximately 30 minutes before”. The tilde is also used to indicate congruence of shapes by placing it over an = symbol, thus ≅.
What does 3 dots mean in math?
therefore sign
In logical argument and mathematical proof, the therefore sign, ∴, is generally used before a logical consequence, such as the conclusion of a syllogism. The symbol consists of three dots placed in an upright triangle and is read therefore.
Does a closed dot mean equal to?
1) Draw a number line. 2) Put either an open circle or a closed dot above the number given. For ≤ and ≥ , use a closed dot to indicate the number itself is part of the solution. For < and >, use an open circle to indicate the number itself is not part of the solution.
How to type mathrel { \\ dot \\ Sim } correctly?
Turns out it is easier to find how to typeset it correctly: tex.SE explains that one should type \\mathrel {\\dot\\sim} instead of simply \\dot\\sim to fix the spacing issue — than to find what it actually means. It has only been used 4 times on CV until now; is it standard?
What does it mean to use dot notation in JavaScript?
Learn about what JavaScript Dot Notation is. Don’t pay much attention to the “notation” part of dot notation, it can make it sound more complex than it is. Dot notation is simply the act of reading or assigning values to an object by using a dot (. ).
When to use a dot over a symbol?
Note that ∼ can be read as “is distributed as” and that adding the dot over a symbol at least sometimes indicates approximation — compare = with = ˙. So ” x ∼ ˙ N ( 0, 1) ” could be read something like ” x is approximately distributed as standard normal”. Personally, I don’t mind the closer spacing in \\dot\\sim ( ∼ ˙) for that use.
