WebbValue (NCV), it is assumed that the products of combustion contained the water vapor and that the heat in the water vapor is not recovered. In other words, the NCV is derived from the GCV by deducting the latent heat of vaporization of water present and formed. Thus, NCV (MJ/kg.) = GCV (MJ/kg.) − 0.222 (% H) . . .

WebbFits a generalized additive model (GAM) to a very large data set, the term ‘GAM’ being taken to include any quadratically penalized GLM (the extended families listed in family.mgcv can also be used). The degree of smoothness of model terms is estimated as part of fitting. In use the function is much like gam, except that the numerical ...
