Configuration

One of the types of objects in Praat.

An object of type Configuration represents the positions of a number of labelled points in a multidimensional space.

## How to create a Configuration

From the New menu:

  • Create Configuration...

By multidimensional scaling:

  • Dissimilarity: To Configuration (monotone mds)...
  • Dissimilarity: To Configuration (i-spline mds)...
  • Dissimilarity: To Configuration (interval mds)...
  • Dissimilarity: To Configuration (ratio mds)...
  • Dissimilarity: To Configuration (absolute mds)...

By multidimensional scaling with weights (Dissimilarity & Weight: To Configuration...):

  • Dissimilarity & Weight: To Configuration (monotone mds)...
  • Dissimilarity & Weight: To Configuration (i-spline mds)...
  • Dissimilarity & Weight: To Configuration (interval mds)...
  • Dissimilarity & Weight: To Configuration (ratio mds)...
  • Dissimilarity & Weight: To Configuration (absolute mds)...

By multidimensional scaling with a start Configuration:

  • Dissimilarity & Configuration: To Configuration (monotone mds)...
  • Dissimilarity & Configuration: To Configuration (i-spline mds)...
  • Dissimilarity & Configuration: To Configuration (interval mds)...
  • Dissimilarity & Configuration: To Configuration (ratio mds)...
  • Dissimilarity & Configuration: To Configuration (absolute mds)...

By transforming an existing Configuration:

  • Configuration: To Configuration (varimax)...
  • Configuration & AffineTransform: To Configuration
  • Configuration & Procrustes: To Configuration

From Principal component analysis:

  • TableOfReal: To Configuration (pca)...
  • PCA & TableOfReal: To Configuration...

From Discriminant analysis:

  TableOfReal: To Configuration (lda)...
  • Discriminant & TableOfReal: To Configuration...

## How to draw a Configuration

  • Configuration: Draw...
  • Configuration: Draw as numbers...
  • Configuration: Draw as squares...

## How to modify a Configuration

  • Configuration: Randomize
  • Configuration: Rotate (pc) (to principal directions)
  • Configuration: Rotate... (in a plane around the origin)
  • Configuration: Invert dimension...
  • Configuration: Normalize...

## Inside a Configuration

With Inspect you will see the following attributes:

numberOfRows
  the number of points (numberOfPoints≥1).
numberOfColumns
  the dimension of the space (numberOfDimensions≥1).
rowLabels
  the names associated with the points.
columnLabels
  the names for the dimensions.
data [1..numberOfPoints] [1..numberOfDimensions]
  the coordinates of the points.
metric
  determines the way distances between points are measured. In general the distance between points xi and xj is:

dij = (∑k=1..numberOfDimensions wk |xik – xjk|metric)1/metric

  For Euclidean distances metric is 2.
w [1..numberOfDimensions]
  weight given to each dimension in the distance calculation.
