I have a question regarding the FPC elements in the Functional Data Explorer. Is there any way that I can extract the formula for those elements? I can only see the formula for the shape functions when I extract the FPCA Model summaries.
Unfortunately I do not know of an easy or straight forward way to do this, although I have many similar use cases.
@Bill_Worley this fits in with our conversation.
Thanks for your reply Elodie. But my question was mainly about the FPC components and the formula to calculate them if I know the shape functions. I have a case that I want to extract the shape functions from some historical data and then use that shape functions to calculate the FPC elements of a new batch. Is there any way around it?
Hi,
It isn't completely straight forward but can be done in a few steps:
1) First, extract the formula by first saving the summaries:
2) From the summary table, you can find all of the Shape Function formulas within the hidden columns of the table:
3) Clicking on the + symbol will open the Formula editor for that column, showing the formula. Double-clicking on it will display it in JSL, which can then be selected and copied:
4) Next, create a new column in your original table, or in a new table with the independent variable in another column (in my case, Time):
5) You can now explore the function in more detail, for example, by plotting it in Graph Builder if you wanted:
Does this do what you were hoping for?
