Simulate error realization from Normal distribution

Simulate error realization from Normal distribution

ec_gen_err_normal(ec_dem, draws, seed = NULL)

Arguments

ec_dem

discrete or volumetric choice data, with or without x

draws

draws from volumetric demand model

seed

seed for reproducible error realisations; seet is automatically reset of running this function

Value

error realizations

Examples

data(icecream)
#run MCMC sampler (use way more than 50 draws for actual use)
icecream_est <- icecream %>% dplyr::filter(id<100) %>% 
vd_est_vdm(R=100, keep=1, error_dist = "Normal")
#> Using 16 cores
#>  MCMC in progress 
#> MCMC complete
#>  Total Time Elapsed: 0.00 minutes
#generate error realizations
errs<- ec_gen_err_normal(icecream %>% dplyr::filter(id<100), icecream_est, seed=123)
