View source: R/simul.commonprob.R

Compute common probabilities of binary random variates generated by thresholding normal variates at 0.

1 | ```
simul.commonprob(margprob, corr=0, method="integrate", n1=10^5, n2=10)
``` |

`margprob` |
vector of marginal probabilities. |

`corr` |
vector of correlation values for normal distribution. |

`method` |
either |

`n1` |
number of normal variates if method is |

`n2` |
number of repetitions if method is |

The output of this function is used by `rmvbin`

. For all
combinations of `marginprob[i]`

, `marginprob[j]`

and
`corr[k]`

, the probability that both components of a normal
random variable with mean `qnorm(marginprob[c(i,j)])`

and
correlation `corr[k]`

are larger than zero is computed.

The probabilities are either computed by numerical integration of the multivariate normal density, or by Monte Carlo simulation.

For normal usage of `rmvbin`

it is not necessary to use
this function, one simulation result is provided as variable
`SimulVals`

in this package and loaded by default.

`simul.commonprob`

returns an array of dimension
`c(length(margprob), length(margprob), length(corr))`

.
