Classifies observed data into differential and non-differential groups based on iNUDGE model.

1 2 | ```
inudge.classify(data, obj, obj.cutoff = 0.1, obj.sigma.diff.cutoff = NULL,
obj.mu.diff.cutoff = NULL)
``` |

`data` |
an |

`obj` |
a list object returned by |

`obj.cutoff` |
optional local |

`obj.sigma.diff.cutoff` |
optional cut-off for standard deviation of the normal component in iNUDGE model to be designated as representing differential. |

`obj.mu.diff.cutoff` |
optional cut-off for standard deviation of the normal component in iNUDGE model to be designated as representing differential. |

A list object passed as input with additional element $class containing vector of classifications for all the observations in data. A classification of 1 denotes that the data is classified as differential with fdr < obj.cutoff.

`mu.diff.cutoff` |
normal component with mean > mu.diff.cutoff was used to represent differential component. |

`sigma.diff.cutoff` |
normal component with standard deviation > sigma.diff.cutoff was used to represent differential component. |
