In particular, as depth increases, if the sizes of the deep grid cells are larger than those in the layers closer to the surface, the number of constructed prisms in each layer decreases progressively over large areas.
They found volatilization of dieldrin tended to decrease as bulk density increased.
When the value of the regularisation parameter is larger than the value of the inflection point, the curve will not fit the model objective well, and the data misfit will be too large.
