Description:
Regression model with 3 QuBiLS-MIDAS descriptors used for the prediction of the Percentage of Repellency, PR, (%) to trigger Aedes aegypti (Yellow Fever Mosquito) spatial repellency at the time of 180 min.

The training was performed with the Vote meta classifier in Weka 3.9.4 with 10-fold cross-validation, by using the “average” combination rule of these base learners: SMOreg, Gaussian Processes (both with Pearson Universal Kernel (PUK)), and Linear Regression. The 3 QuBiLS-MIDAS descriptors are namely:

GV[1]_S_Q_AB_nCi_2_M13_NS1_o_C_KA_r_MID
I50_B_AB_nCi_2_M8_SS1_T_KA_a-p_MID
Q2_F_AB_nCi_2_M14_SS8_T_KA_e_MID

Training set:
14 compounds extracted from 10.1021/jf900964e

Performance:
For a 10-fold cross-validation, the statistical parameters (performance without applicability domain) are R = 0.7788, MAE = 5.985, RMSE = 8.5684, RAE = 48.6287 %, and RRSE = 57.8021 %.

Classification Breakpoint:
The breakpoint is 90 %. Values greater than or equal to the breakpoint will elicit a repellent response in Blatella germanica and Periplaneta americana cockroaches. Lower values represent certain actions occurring, however, these are not enough to activate a repellent reaction.
