Names and breakpoints for the 4 histogram benchmark distributions from Rozenholc/Mildenberger/Gather (2010).

`dnum` |
number of distribution. |

These functions implement the 4 histogram benchmark distributions from Rozenholc/Mildenberger/Gather (2010). Defined as the following mixtures of uniform distributions:

`dnum == 1`

5 bin regular histogram:

*0.15*U[0,0.2] + 0.35*U(0.2,0.4] + 0.2*U(0.4,0.6] +0.1*U(0.6,0.8]+ 0.2*U(0.8,1.0]*

`dnum == 2`

5 bin irregular histogram:

*0.15*U[0,0.13] + 0,35*U(0.13,0.34] + 0.2*U(0.34,0.61]
+0.1*U(0.61,0.65] + 0.2*U(0.65,1.0]*

`dnum == 3`

10 bin regular histogram:

*0.01*U[0,0.1] + 0.18*U(0.1,0.2] + 0.16*U(0.2,0.3]*

*+0.07*U(0.3,0.4] + 0.06*U(0.4,0.5] + 0.01*U(0.5,0.6]*

*+0.06*U(0.6,0.7] + 0.37*U(0.7,0.8] + 0.06*U(0.8,0.9]*

*+0.02*U(0.9,1.0]*

`dnum == 4`

10 bin irregular histogram:

*0.01*U[0,0.02] + 0.18*U(0.02,0.07] + 0.16*U(0.07,0.14]*

*+0.07*U(0.14,0.44] + 0.06*U(0.44,0.53] + 0.01*U(0.53,0.56]*

*+0.06*U(0.56,0.67] + 0.37*U(0.67,0.77] + 0.06*U(0.77,0.91]*

*+0.02*U(0.91,1.0] *

where *U[a,b]* denotes the uniform distribution on *[a,b]*.

`nhisto` |
gives the name of the distribution (the same as |

`bhisto` |
gives the vector of break points (the same as |
