# decreasing

### Description

Returns the log-maximum likelihood and the estimator of the mean under the monotone decreasing profile.

### Usage

1 | ```
decreasing(data,x,n.rep)
``` |

### Arguments

`data` |

`x` |
A vector consisting of the average expression at time points (1, 2,... ,T), where T is the total number of time points. |

`n.rep` |
A vector consisting of the number of replicate arrays at time points (1, 2,... ,T), where T is the total number of time points. |

### Value

`logelr` |
Log-maximum likelihood |

`mu` |
A vector containing the estimator of the mean |
