A logistic regression model is fitted to the linear scores using lrm() function and the logistic scores are computed using the formula: 1/(1+exp(-(a+bX))) where a and b are the logistic coefficients.

1 2 | ```
compute.logistic.score(F_, L_, considered.features, training.samples, validating.samples,
linear.scores, report.fitting.failure = TRUE)
``` |

`F_` |
The feature matrix, each column is a feature. |

`L_` |
The vector of labels named according to the rows of F. |

`training.samples` |
The names of rows of F that should be considered as training samples. |

`validating.samples` |
The names of rows of F that should be considered as validating samples. |

`considered.features` |
The names of columns of F that determine the features of interest. |

`linear.scores` |
A vector that contains for each training or validating sample, a linear score predicted by the linear method. |

`report.fitting.failure` |
If TRUE, any failure in fitting the linear of logistic models will be printed. |

The logistic regression will be fitted to all training and validating samples.

Returns a list of:

`logistic.scores` |
A vector of predicted logistic values for all samples. |

`logistic.cofs` |
The coefficients that are computed by logistic regression. |

Logistic regression is also done on top of fitting the linear models.
