More often the number of va.ia.les a.d the qua.tified vola.ile compounds exceed the number of observa.ions or sa.ples a.d hence ma.y tra.itiona. sta.istica. a.a.ysis methods become inefficient. Here, we employed ma.hine lea.ning a.gorithm, ra.dom forest (RF) in combina.ion with dista.ce-ba.ed procedure, simila.ity percenta.e (SIMPER) a. preprocessing steps to reduce the da.a.dimensiona.ity in the chemica. profiles of vola.iles from three a.rica. nightsha.e pla.t species before subjecting the da.a.to non-metric multidimensiona. sca.ing (NMDS).

The novelty of our work is on the merits of using da.a.reduction techniques to successfully revea. differences in groups which could ha.e otherwise not been the ca.e if the a.a.ysis were performed on the entire origina. da.a.ma.rix cha.a.teriz.d by sma.l sa.ples.
