Request for Multidimensional Scaling (MDS) #217

Open rflidster opened 6 years ago

rflidster commented 6 years ago

Enhancement: To include Multidimensional Scaling (MDS) functionality in JASP

Ideally, functions would include:

Fit indices such as R^2 and stress, including plots for evaluating fit in different dimensions and evaluating dimensionality of the data
Plots of the resulting data points in 1-, 2-, or 3-dimensional space
Means of rotating the points in 2- or 3-dimensional space
Purpose: Commonly used tool to analyze perceptual data. JASP's existing functions are already very close to doing this.

My sincere thanks for your consideration and time.

@rflidster, sorry for the very late response. Do you mean stuff that is included in the factor module?

rflidster commented 1 year ago

I'm not sure I understand what you mean. I'm thinking of something like the MSCAL function in SPSS or like this in R: http://www.sthda.com/english/articles/31-principal-component-methods-in-r-practical-guide/122-multidimensional-scaling-essentials-algorithms-and-r-code/

Yes, including MDS is a good idea.

This package is particularly useful and contains a very comprehensive set of features:

This would be very nice to have.
