Given a sequence of desired stats return a map of statname->value.

Example:

cljs.user> (dfn/descriptive-statistics [:min :max :mean :n-values] (range 10))
{:min 0, :max 9, :mean 4.5, :n-values 10}

Euclidian distance between x,y

Euclidian distance squared between x,y

Numeric equals - the distance between x,y must be less than error-bar which defaults to 0.001.

Magnitude of the vector

Magnitude-squared of the vector

Nan-aware mean. Nan's will be skipped.

Nan-aware median. Nan's will be skipped.

Percentiles are given in whole numbers:

tech.v3.datatype.functional> (percentiles [0 25 50 75 100] (range 10))
[0.0 1.75 4.5 7.25 9.0]

return min, 25 50 75 max of item

Nan-unaware max. tech.v3.datatype.statistics/max is nan-aware

Nan-unaware min. tech.v3.datatype.statistics/min is nan-aware

NaN-aware eq

Shift by n and fill in with the first element for n>0 or last element for n<0.

Examples:

user> (dfn/shift (range 10) 2)
[0 0 0 1 2 3 4 5 6 7]
user> (dfn/shift (range 10) -2)
[2 3 4 5 6 7 8 9 9 9]

Nan-aware standard-deviation. Nan's will be skipped.

Nan-aware sum. Nan's will be skipped.

Nan-aware variance. Nan's will be skipped.
