Table 3.

The average, absolute error in the T_g values predicted by equation (1) for the three polymer classes found in Figure 1 at k=50%.

Polymer class	Polymers	Set size	k mina	ΔTav: Average Tg prediction error (K)
I	All polycarbonates and polyarylates	100	7b	6.4
II	Poly(DTE-co-DT-co-PEG carbonate)s	13	7	5.3
III	Poly(I2DTE-co-I2DT-co-PEG carbonate)s	19	7	3.7

^aThe minimum size of the construction set (in nr of X,Y pairs) necessary to obtain the best T_g prediction (lowest ΔT_av) in that class

^bNo asymptotic behavior, arbitrarily chosen value of k
