StephenAshley.Biostatistics.FriedmanGroupsCollection.FriedmanGroupsCollection | ( | ) |

Constructs an empty FriedmanGroupsCollection.

Definition at line 23 of file FriedmanGroupsCollection.cs.

StephenAshley.Biostatistics.FriedmanGroupsCollection.FriedmanGroupsCollection | ( | List< Group > | groups |
) |

Constructs a FriedmanGroupsCollection from a list of Group objects.

**Parameters:**-
*groups*The Group objects.

Definition at line 30 of file FriedmanGroupsCollection.cs.

override void StephenAshley.Biostatistics.FriedmanGroupsCollection.Add | ( | Group | group |
) | ` [virtual]` |

Adds a Group to the FriedmanGroupsCollection.

**Parameters:**-
*group*The Group.

**Exceptions:**-
*BiostatisticsException*• the Group is a null reference, • the Group has no members, or

• the size of the Group is different from the sizes of the other Group objects.

Reimplemented from StephenAshley.Biostatistics.GroupsCollection.

Definition at line 41 of file FriedmanGroupsCollection.cs.

NUMBER StephenAshley.Biostatistics.FriedmanGroupsCollection.CriticalValue | ( | ) |

Returns a value for p for the FriedmanGroupsCollection.

p is calculated from a table of critical values based on Jerrold H. Zar, Biostatistical Analysis Table B.14 (5th ed. 2010 [sic]). If this method returns a critical value of p, use that value to evaluate the treatments. If the FriedmanGroupsCollection is outside the range of the table of critical values and an exception is thrown, use p based on the χ² distribution.

**Returns:**- p.

**Exceptions:**-
*BiostatisticsException*the FriedmanGroupsCollection contains fewer than 2 subjects. the FriedmanGroupsCollection contains fewer than 2 treatments.

GroupsCollection.k is outside the range of the critical values table.

N is outside the range of the critical values table.

Definition at line 138 of file FriedmanGroupsCollection.cs.

Int32 StephenAshley.Biostatistics.FriedmanGroupsCollection.DegreesOfFreedom | ( | ) |

The degrees of freedom of the FriedmanGroupsCollection.

**Returns:**- The degrees of freedom.

**Exceptions:**-
*BiostatisticsException*The FriedmanGroupsCollection contains no Group objects.

Definition at line 72 of file FriedmanGroupsCollection.cs.

NUMBER StephenAshley.Biostatistics.FriedmanGroupsCollection.FriedmanStatistic | ( | ) |

Returns the Friedman statistic (χ²r).

**Returns:**- The statistic

**Exceptions:**-
*BiostatisticsException*The FriedmanGroupsCollection has fewer than 2 subjects, The FriedmanGroupsCollection has fewer than 2 treatments.

Definition at line 92 of file FriedmanGroupsCollection.cs.

Int32 StephenAshley.Biostatistics.FriedmanGroupsCollection.N | ( | ) |

Returns the number of subjects in the FriedmanGroupsCollection.

**Returns:**- The number.

Definition at line 180 of file FriedmanGroupsCollection.cs.

NUMBER StephenAshley.Biostatistics.FriedmanGroupsCollection.p | ( | ) |

Returns the statistic p for the FriedmanGroupsCollection based on the χ² distribution.

If CriticalValue returns a value for p, use that value rather than the value returned by p, as the χ² distribution is not an accurate approximation for small values of N.

**Returns:**- p.

Definition at line 196 of file FriedmanGroupsCollection.cs.

NUMBER [] StephenAshley.Biostatistics.FriedmanGroupsCollection.SumsOfRanks | ( | ) |

Returns an array containing the sums of the ranks for each treatment.

**Returns:**- The array.

**Exceptions:**-
*BiostatisticsException*The FriedmanGroupsCollection contains no Group objects.
