The DoublePCA type exposes the following members.
Constructors
| Name | Description | |

Methods
| Name | Description | |
|---|---|---|
| Clone |
Creates a deep copy of this principal component analysis.
| |
| Equals | (Inherited from Object.) | |
| GetHashCode |
Serves as a hash function for a particular type.
(Inherited from Object.) | |
| GetType |
Gets the Type of the current instance.
(Inherited from Object.) | |
| Threshold |

proportion of the total variance.

Properties
| Name | Description | |
|---|---|---|
| CumulativeVarianceProportions |
Gets the cumulative variance proportions.
| |
| Data |
Gets the data matrix.
| |
| Eigenvalues |
Gets the eigenvalues of the covariance/correlation matrix, though the
calculation is actually performed using the singular values of the data
matrix.
| |
| IsCentered |
Returns true if the data supplied at construction time was
shifted to be zero-centered.
| |
| IsScaled |
Returns true if the data supplied at construction time was
scaled to have unit variance.
| |
| Item |
Gets the specified principal component.
| |
| Loadings |
Gets the loading matrix. Each column is a principal component.
| |
| Means |
Gets the column means of the data matrix.
| |
| Norms |
Gets the column norms (1-norm).
| |
| NumberOfObservations |
Gets the number of observations in the data matrix.
| |
| NumberOfVariables |
Gets the number of variables in the data matrix.
| |
| Scores |
Gets the score matrix.
| |
| StandardDeviations |
Gets the standard deviations of the principal components.
| |
| VarianceProportions |
Gets the proportion of the total variance accounted for by each
principal component.
