# Cool Statistical Term Names

I thought it might be fun to draft a list of cool names for statistical terms/procedures. Since some of us may not be familiar with them or know their meanings.

Bootstrap (a play on pulling yourself up by your bootstrap - resampling procedure)
Random Forrest (using bootstrap while performing regression trees)
BAgging (bootstrap aggregating with regression trees, bootstrapping variables as well)

I can't remember whether the Jackknife has a cool definition or not?

#### vinux

##### Dark Knight
Boosting
BLUE (best linear unbiased estimator)
MIDAS (Mixed data sampling)
Hat Matrix
Agnes (agglomerative nesting : clustering)
Diana (DIvisive ANAlysis :Clustering)

(will add the details later )

Yes, I like how the hat matrix puts hats on things!

Hat matrix would be an awesome Halloween costume. You could carry around a bunch of cheap hats and put them on people at the Halloween party.

Or what about a matrix filled with different types of hats.

Hat_matrix <- (baseball_hat, cowboy_hat, beret, ski_mask, rows=2)

So OOB means the test set, so it wasn't in the bagging process?

You know you made it in academics when you can coin acronyms

HVRPFSUDAPCR is not a stats term but is a military acronym I believe...if you know what it stands for (its a type of ammo) you seriously need to get a life

I was thinking that we over look how cool the following are:

ANOVA

MANOVA

#### spunky

##### Doesn't actually exist
it doesn't pertain only to statistics (many other sciences show this instance) but i've always liked the concept of...

LAPLACE'S DEMON

mwahahahahahahahahaha!!!

I will follow you up with another haunting phrase:

The curse of multi-dimensionality

In causal diagrams

Collider/M-Bias (inverted fork):
variable with respect to a particular path and there are two variables along the path with arrows that both point to the it (collider).

Confounder: common ancestor of two connected variables

Butterfly Bias: causal model with both confounding and M-bias (looks like a butterfly)

Occam's Razor is nice as well.

#### Jake

Copula, which sounds like the noun form of copulation, but is disappointingly not.
