`teleport_prob` |
Probability of 'teleportation'. |

`stoch` |
Input stochastic matrix. |

Modification logic behind `teleport()`

assumes that at each step
of Markov chain (described by column-stochastic matrix) the decision is made
whether to change state according to stochastic matrix or to 'teleport' to
any state with equal probability. Probability of 'teleport' is
`teleport_prob`

. This modification is useful because it ensures
irreducibility of stochastic matrix (with `teleport_prob`

in (0; 1)).
**Note** that in order to obtain modifier one should call function
`teleport()`

with some parameter.

`vote_equal()`

and `vote_self()`

modify columns with elements only equal to
0. The former fills them with `1/nrow(stoch)`

and the latter changes only the
respective diagonal element to 1. This is equivalent to jump to any state
with equal probability and to stay in the current state respectively.

`teleport()`

returns a modifier function.

`vote_equal()`

and `vote_self()`

are modifier functions and return modified
version of input stochastic matrix.
