We analyze the spectral energy distributions (SEDs) and emission lineproperties of the red (J-K$_S$ > 2) 2MASS AGN observed by Chandra usingprinciple component analysis. The sample includes 44 low redshift AGN with lowor moderate obscuration (N_H < 10^{23} cm^{-2}) as indicated by X-rays and SEDmodeling. The obscuration of the AGN allows us to see weaker emissioncomponents (host galaxy emission, AGN scattered light) which are usuallyoutshone by the AGN. The first four eigenvectors explain 70% of the variance inthe sample. The dominant cause of variance in the sample (eigenvector 1) is theL/Ledd ratio strengthened by intrinsic absorption. Eigenvector 2 is related tohost galaxy (relative to the observed AGN) emission and eigenvectors 3 and 4distinguish between two sources of obscuration: host galaxy absorption andcircumnuclear absorption. Although our analysis is consistent with unificationschemes where inclination dependent obscuration is important in determining theAGN SEDs, the L/Ledd ratio is the most important factor, followed by hostgalaxy emission.
