Iterative Log Mean Centering Normalization requires only a standard deviation |
2 |
26 Feb 07 |

8 |
range to be selected. During each iteration the a mean log ratio and standard deviation is |
2 |
26 Feb 07 |
jari |
9 |
taken on a subset of the data which is initially the entire data set. The calculated mean |
2 |
26 Feb 07 |

10 |
is used to correct the position to move the mean toward zero. |

At the end of each iteration, data elements within the indicated standard deviation range are |
2 |
26 Feb 07 |
jari |
12 |
selected to enter the next iteration and are used to calculate a current mean and standard deviation. |
2 |

Iterations stop when the mean converges to zero. |

Using small values for standard deviation will force the subset of data used for the |

next iteration to be a more aggressive cut of the data. |
