how can I do PCA on a table ?
20 views (last 30 days)
I have a 3000 x 18 table containing 18 variables (one per column) of both numerical and categorical type (6 categorical).
I would liket to do PCA on the whole dataset
but the command
[coeff,score]=pca(mytable) does not work.
any idea on how to proceed ?

The pca function only accepts single-precision or double-precision numerical arrays. You most likely need to use the table2array (link) function first, to get the numeric data out of your table and into a form that pca can use.
