## Margins cdf/pdf and their derivatives

### Description

```

### Arguments

model for margin: "binomial" (bernoulli), "poisson", "nbinom" (mean is the parameter),"nbinom1" (p is the parameter), "geometric", "multinomial", "exponential", "weibull", "normal","t", "laplace" |

`x` |
covariates for the multinomial margin (default is NULL) |

`dfM` |
