[Function]

compose

f g

[Function]

Return a function h such that (h x) = (f (g x)).

average

list &key (key (function identity))

[Function]

the average of a list

%fast-average

list

[Function]

median

list &key (already-sorted nil) (key (function identity))

[Function]

the median of a list

stdev

list &key average (key (function identity))

[Function]

%fast-stdev

list average

[Function]

correlation

datapoints

[Function]

Datapoints should be a list of (x . y) pairs. Returns values a,b,r**2 for which y=a+bx is a least square fitting with the square of the correlation coefficient equal to r**2.

fac!

nr &optional (start 1)

[Function]

permutations

a &optional (b a)

[Function]

The number of permutations of length b out of a

combination

a b

[Function]

The combination for b out of a

count-subsets

[Function]
