[SOLVED] Multiple Output

Hey there,

my task is to predict frequency spectra from two different measurements. I measure with 3 sensors, so each measurement has 3 entries as columns.
A was measured under an different environment than B.

The data have the following shape:
Measurement A: Measurement B: The thesis is that I can use a stochastic approach to predict B using A. So I make a measurement C under the same conditions as A and want to use RM to predict D (which will have the same environment as .

I hope you understand what I want to try.

The question is now how I can realize this with RM. I already thought Multi Label is the answer, but apparently I misunderstood what it does.
Is it even possible to create D with its three column? Do you have any advice?

Thanks in advance!
