There is a good agreement between
the Seager equation and the special basic model. There is a good correspondence of the Seager equation with the Drakecorrected Special Basic Model. This confirms that the special basic model and the transformed Seager equation represent two equivalent approaches. There is a good agreement between the Drake equation and the corrected basic general model. This confirms that the General Basic Model and the Drake equation represent two equivalent approaches. The compatibility of the Drakecorrected basic general model with the Seagercorrected basic general model is also evident.
