I am wondering whether it is possible to project new data to an existing PCA map. Per my limited knowledge with PCA map generation I do not think it is the case. But want to check with JMP community on this.
The context is that we generated a map using objective data on 20 products with 30 variables. Let's say after an year we want to project data from 3 new products with same 30 variables to the existing PCA map. Is it posisble with PCA approach? Are there any other solutions to achieve this ?
Thanks in adavance for any thoughts and suggetsions.
Click the red triangle next to Principal Components and select Save Columns > Save Principal Components. It saves the formula that multiplies the data column by the eigenvectors to obtain the score. It works with new observations.
