P.logdet() returns the natural logarithm of the additive numerator relationship matrix.
2.6.5 rela
P.rela() returns the additive numerator relationship matrix.
2.6.6 reld
P.reld() returns the dominant relationship matrix, assuming no no inbred individuals.
2.6.7 inv
P.inv() returns the inverse of the additive relationship matrix.
2.6.8 size
P.size() returns the total number of individuals in pedigree P.

2.7 Data Object
A Data object in Matvec is a object which can handle a dataset. Data class in still under development. A
data object can be created by D = Data(). Then, use its member function input to input data from disk
into the object.
2.8 Model Object
A model object can be created by M = Model(). Then, use its member function equation to specify the
linear model equations. Other characteristics for the model such as random effect, covariate, etc. can be
specified through appropriate member functions.
For example,
> M = Model();
> M.equation("y = herd animal");
2.9 StatDist Object
