BASS.generalized(sales, shock = c("exp", "rett", "mixed", "harmonic"),
                 nshock, prelimestimates, alpha = 0.05, ous = 100,

`sales`	Instantaneous sales
`shock`	Function characterizing the shock. Available options are: Exponential ('exp'), Rectangular ('rett'), Harmonic ('harmonic') and Mixed ('mixed').
`nshock`	Number of shocks desired (from 1 to 3)
`prelimestimates`	Vector containing the preliminary estimates of the parameters
`alpha`	Desired significance level, the default value is 0.05
`ous`	Numeric value for the out-of-sample forecasts, the default value is 100
`display`	T or F, to display the plot of the model or not, the default value is T
`max.iter`	Maximum number of iterations, the default value is 100
