StephenAshley.Biostatistics.PairedT_TestGroupsCollection.PairedT_TestGroupsCollection

(

List< Group >

groups

)

Creates a PairedT_TestGroupsCollection from a list of Group objects.

Parameters:

groups

The Group objects.

Exceptions:

Biostatistics

• groups is a null reference, • the PairedT_TestGroupsCollection contains more than two Group objects, or • the second Group does not have as many members as the first Group.

Member Function Documentation

override void StephenAshley.Biostatistics.PairedT_TestGroupsCollection.Add

(

Group

group

)

[virtual]

Adds a Group to the PairedT_TestGroupsCollection.

Parameters:

group

A Group.

Exceptions:

BiostatisticsException

• group is a null reference, • addition of group would result in a PairedT_TestGroupsCollection with more than 2 Group objects.

Reimplemented from StephenAshley.Biostatistics.T_TestGroupsCollection.

override void StephenAshley.Biostatistics.PairedT_TestGroupsCollection.AddRange

(

List< Group >

lstGroups

)

[virtual]

Adds a list of Group objects to the PairedT_TestGroupsCollection.

Parameters:

lstGroups

A List of Group objects.

Exceptions:

BiostatisticsException

• lstGroups is a null reference, • lstGroups contains no Group objects • addition of Group objects would result in a PairedT_TestGroupsCollection with more than 2 Group objects, or • addition of Group objects would result in a PairedT_TestGroupsCollection with Group objects of unequal sizes.
