Log-Likelihood for conjunctive-screening volumetric demand model — vd_LL_vdm_screen • echoice2

Log-Likelihood for conjunctive-screening volumetric demand model

vd_LL_vdm_screen(draw, vd, fromdraw = 1)

Arguments

draw: A list, 'echoice2' draws object
vd: A tibble, tidy choice data (before dummy-coding)
fromdraw: An integer, from which draw onwards to compute LL (i.e., excl. burnin)

Value

N x Draws Matrix of log-Likelihood values

Examples

data(icecream)
#fit model
icecream_est <- icecream %>% filter(id<20) %>% vd_est_vdm_screen(R=10, keep=1, cores=2)
#> Using 2 cores
#>  MCMC in progress 
#> MCMC complete
#>  Total Time Elapsed: 0.00 minutes
#compute likelihood for each subject in each draw
loglls<-vd_LL_vdm_screen(icecream_est, icecream%>% filter(id<20), fromdraw = 2)
dim(loglls)
#> [1] 19 10
