bincount
extends UFunc
A breeze.generic.UFunc for counting bins.
A breeze.generic.UFunc for counting bins.
If passed a traversable object full of Int's, provided those ints are larger than 0, it will return an array of the bin counts. E.g.: bincount(DenseVector[Int](0,1,2,3,1,3,3,3)) == DenseVector[Int](1,2,1,4)
One can also call this on two dense vectors - the second will be treated as an array of weights. E.g.: val x = DenseVector[Int](0,1,2,3,1) val weights = DenseVector[Double](1.0,2.0,1.0,7.0,1.0) result is bincount(x, weights) == DenseVector[Double](1.0,3.0,1,7.0)

digitize
extends UFunc
A breeze.generic.UFunc for digitizing arrays.
A breeze.generic.UFunc for digitizing arrays.
Each element in the bins array is assumed to be the *right* endpoint of a given bin. For instance, bins=[1,3,5] represents a bin from (-infty,1], (1,3], (3,5] and (5,\infty). The result returned is the index of the bin of the inputs.
E.g., digitize([-3, 0.5, 1, 1.5, 4], [0,1,2]) = [0, 1, 1, 2, 3]

object
mean
extends UFunc
A breeze.generic.UFunc for computing the mean of objects
-
object
meanAndVariance
extends UFunc
A breeze.generic.UFunc for computing the mean and variance of objects.
A breeze.generic.UFunc for computing the mean and variance of objects. This uses an efficient, numerically stable, one pass algorithm for computing both the mean and the variance.

object
median
extends UFunc
A breeze.generic.UFunc for computing the median of objects
- object mode extends UFunc

object
stddev
extends UFunc
Computes the standard deviation by calling variance and then sqrt'ing
-
object
variance
extends UFunc
A breeze.generic.UFunc for computing the variance of objects.
A breeze.generic.UFunc for computing the variance of objects. The method just calls meanAndVariance and returns the second result.
