Hi,I'm using PCA for dimensionality reduction purposes. I have a large data set of 5,000 models / columns to be reduced to 5-10 models / columns.I have watched various instructional youtube videos on XLSTAT PCA and followed the user guide however I fail to understand how to reduce the data to the 5-10 models I require.Please adviseRoss
Each dimension that arises from PCA does not necessarily represent one single column in your original dataset. PCA dimensions carry information provided by bunches of real variables.
I suggest that you watch the recording on exploratory statistics that can be found here:
XLSTAT first steps and statistical learning resources
The place where you will master all of XLSTAT features
Any feature or option you’d like us to develop?
