Orange Canvas: Principal Components Analysis widget?

Postby BarryFordham » Tue Feb 21, 2012 7:26

Hi. I'm a new Orange user. I could not see a widget for Principal Components Analysis on the Orange Canvas, even though PCA is listed in the Reference. I would like to use a widget for this as I find it them to use - I have not tried to use scripting and am not confident that I will be able to. Cheers, Barry Fordham.

PCA is implemented as part of Linear Projection widget. Inside the widget click the FreeViz button and in the dialog click the "Projection" tab, then click the "Principal component analysis".
