# Class "PosteriorProbabilities"

### Description

This S4 class summarizes the posterior probabilities over time for objects
of class `"ArtCohort"`

### Usage

1 2 3 4 5 6 7 8 9 10 11 12 13 14 | ```
## S4 method for signature 'PosteriorProbabilities,ANY,ANY,ANY'
x[i, j, ..., drop = TRUE]
## S4 method for signature 'PosteriorProbabilities'
plot(x, ci = FALSE, main = paste(x@type,
"after starting in State", x@states[1], "at time 0"),
states = 1:dim(x@probabilities)[2], lwd = c(2, 2), col = c("blue",
"green3"), lty = c(1, 2), xlab = "Time", ylab = "Probability", ...)
## S4 method for signature 'PosteriorProbabilities'
head(x, ...)
## S4 method for signature 'PosteriorProbabilities'
tail(x, ...)
``` |

### Arguments

`x` |
the PosteriorProbabilities object |

`i, j, drop` |
same as for a |

`...` |
arguments passed on to main method |

`ci` |
should confidence intervals be displayed |

`main, xlab, ylab` |
same as any plot |

`states` |
which states to display |

`lwd, col, lty` |
vectors of lentht 2, with first component for the point estimate and second component for the confidence interval |

### Slots

Object of class

`"numeric"`

: time points at which probabilities are evaluated`probabilities`

Object of class

`"matrix"`

: posterior Probabilities to be in each state at each time`lower`

Object of class

`"matrix"`

: lower prediction bound to be in each state at each time`upper`
