emissions_model1 | R Documentation |
gamma distribution of emissions above a cutoff corresponding to input mean emissions and standard deviation parameters. Dependence on mileage is modelled by a tanh function.
emissions_model1( mileage, mean_emissions = 190, sd_emissions = 30, e_cut = 80, zeta = 0.75 )
mileage |
km |
mean_emissions |
gco2/km - corresponds to wltm emissions e.g. 190gCO2/km in 2015 |
sd_emissions |
gco2/km - |
e_cut |
lower bound on ICEV emissions, roughly set to Toyota Prius wltp emissions |
zeta |
determines strength of correlation between mileage and emissions |
a randomly generated specific emissions in gCO2/km
