## Joint Probabilities for Crossings and Runs, Symmetric Case

### Description

Joint probability distribution for the number of crossings
C and the longest run L in a sequence of n independent Bernoulli observations
with success probability p. To enhance precision, results are stored
in mpfr arrays and the probabilities are multiplied by `m^{n-1}`

for a multiplier m. This is for the symmetric case with success
probability 0.5, in which the multiplied probabilities are
integers for the default value 2 of the multiplier.

### Usage

```
crossrunsymm(nmax = 100, mult = 2, prec = 120, printn = FALSE)
```

### Arguments

`nmax` |
; max sequence length. |

`mult` |
; multiplier for joint probabilities. Default 2. |

`prec` |
; mpft precision. |

`printn` |
; logical for including progress output. |

### Value

pt, list of joint probabilities, multiplied with `m^{n-1}`

.
In addition cumulative probabilities qt within each row are also included.

### Examples

```
crs10 <- crossrunsymm(nmax=10,printn=TRUE)
```
