## Default parameters for logistic regression model in sevenC.

### Description

This dataset contains term names and estimates for logistic regression model to predict chromatin looping interactions. The estimate represent an average of the 10 best performing models out of 124 transcription factor ChIP-seq data sets from ENCODE.

### Usage

    modelBest10Avg

### Format

An object of class `data.frame` with 7 rows and 2 columns holding the term name and estimate.

(Intercept)

  The intercept of the logistic regression model.

dist

  The genomic distance between the centers of motifs in base pairs (bp).

strandOrientationdivergent

  Orientation of motif pairs. 1 if divergent 0 if not.

strandOrientationforward

  Orientation of motif pairs. 1 if forward 0 if not.

strandOrientationreverse

  Orientation of motif pairs. 1 if reverse 0 if not.

score_min

  Minimum of motif hit score between both motifs in pair. The motif score is defined as -log_10 of the p-value of the motif hit as reported by JASPAR motif tracks. The unit is -log_10(p) where p is the p-value of the motif hit.

cor

  Pearson correlation coefficient of ChIP-seq signals across +/- 500 bp around CTCF motif centers.

### Details

Each of 124 transcription factor (TF) ChIP-seq data sets from ENCODE in GM12878 cells were used to train a logistic regression model. All CTCF motifs in `motif.hg19.CTCF` within a distance of 1 Mb were used as candidates. A given pair was labled as true loop interactions, if it has interaction support based on loops from Hi-C in human GM12878 cells from Rao et al. 2014 or ChIA-PET loops from Tang et al. 2015 in the same cell type. The 10 best performing models were selected based on the average area under the precision-recall-curve in 10-fold cross-validation. The parameters were than averaged across the 10 best performig models.
