Running 4999 simulations 16 three different weights specifications parametric permutation bootstrap takes quite lot time. collate results compare analytical standard deviates Normality randomisation, see fact differences large, expressed median absolute difference tables. can also see inferences based one-sided α=0.05\\alpha=0.05 cut-analytical bootstrap approaches. indicates can, general, rely analytical standard deviates, bootstrap methods help assumptions underlying measures met. assumptions affect shape distribution measure tails; one possibility use Saddlepoint approximation find equivalent analytical bootstrap-based standard deviate inference (Tiefelsdorf 2002). Saddlepoint approximation requires eigenvalues weights matrix iterative root-finding global Moran’s II, local Moran’s IiI_i, analytical forms known. Even computational burden, Saddlepoint approximation global Moran’s II runs quite quickly. First need fit null linear models (including intercept) variables, apply lm.morantest.sad fitted model objects: Although analytical standard deviates (Normality) larger reached using Saddlepoint approximation measured median absolute deviation, differences lead different inferences chosen cut-. reflects fact shape distribution sensitive small nn, moderate nn global Moran’s II, effects seen tails. consequences local Moran’s IiI_i much stronger, clique neighbours observation typically small. perhaps interest differences much smaller case general weights unstandardised binary weights. addition choose use exact distribution Moran’s II, described Tiefelsdorf (2000); implementation covered R. S. Bivand, Müller, Reder (2009). global case also needs eigenvalues weights matrix, solution numerical integration function, cases, timings quite acceptable. output comparable Saddlepoint approximation, inferences drawn chosen cut-analytical standard deviates calculated Normality. Li, Calder, Cressie (2007) take challenge Cliff Ord (1969, 31), try give statistic bounded fixed range. APLE measure intended approximate spatial dependence parameter simultaneous autoregressive model better Moran’s II, re-scales measure function eigenvalues spatial weights matrix. APLE requires use row standardised weights. order save time, use two internal functions spatialreg:::preAple spatialreg:::inAple, since definition spatial weights, eigenvalue calculations need made. notation using ::: operator says function named operator found namespace package named operator. APLE values repeat pattern already seen — variables, measured autocorrelation similar irrespective spatial weights definition, others, change definition binary general make difference.","code":"MoranI.boot <- function(var, i, ...) {   var <- var[i]   return(moran(x=var, ...)$I) } Nsim <- function(d, mle) {   n <- length(d)   rnorm(n, mle$mean, mle$sd) } f_bperm <- function(x, nsim, listw) {   boot(x, statistic=MoranI.boot, R=nsim, sim=\"permutation\", listw=listw,     n=length(x), S0=Szero(listw)) } f_bpara <- function(x, nsim, listw) {   boot(x, statistic=MoranI.boot, R=nsim, sim=\"parametric\", ran.gen=Nsim,     mle=list(mean=mean(x), sd=sd(x)), listw=listw, n=length(x),     S0=Szero(listw)) } nsim <- 4999 set.seed(1234) system.time({ MoranNb <- lapply(vars, function(x) f_bpara(x=eire_ge1[[x]], nsim=nsim, listw=nb_B)) MoranRb <- lapply(vars, function(x) f_bperm(x=eire_ge1[[x]], nsim=nsim, listw=nb_B)) Prop_unstdNb  <- lapply(vars, function(x) f_bpara(x=eire_ge1[[x]], nsim=nsim, listw=lw_unstand)) Prop_unstdRb  <- lapply(vars, function(x) f_bperm(x=eire_ge1[[x]], nsim=nsim, listw=lw_unstand)) Prop_stdNb  <- lapply(vars, function(x) f_bpara(x=eire_ge1[[x]], nsim=nsim, listw=lw_std)) Prop_stdRb  <- lapply(vars, function(x) f_bperm(x=eire_ge1[[x]], nsim=nsim, listw=lw_std)) }) res <- lapply(c(\"MoranNb\", \"MoranRb\", \"Prop_unstdNb\", \"Prop_unstdRb\", \"Prop_stdNb\", \"Prop_stdRb\"), function(x) sapply(get(x), function(y) (y$t0 -

Running 4999 simulations 16 three different weights specifications parametric permutation bootstrap takes quite lot time. collate results compare analytical standard deviates Normality randomisation, see fact differences large, expressed median absolute difference tables. can also see inferences based one-sided α=0.05\\alpha=0.05 cut-analytical bootstrap approaches. indicates can, general, rely analytical standard deviates, bootstrap methods help assumptions underlying measures met. assumptions affect shape distribution measure tails; one possibility use Saddlepoint approximation find equivalent analytical bootstrap-based standard deviate inference (Tiefelsdorf 2002). Saddlepoint approximation requires eigenvalues weights matrix iterative root-finding global Moran’s II, local Moran’s IiI_i, analytical forms known. Even computational burden, Saddlepoint approximation global Moran’s II runs quite quickly. First need fit null linear models (including intercept) variables, apply lm.morantest.sad fitted model objects: Although analytical standard deviates (Normality) larger reached using Saddlepoint approximation measured median absolute deviation, differences lead different inferences chosen cut-. reflects fact shape distribution sensitive small nn, moderate nn global Moran’s II, effects seen tails. consequences local Moran’s IiI_i much stronger, clique neighbours observation typically small. perhaps interest differences much smaller case general weights unstandardised binary weights. addition choose use exact distribution Moran’s II, described Tiefelsdorf (2000); implementation covered R. S. Bivand, Müller, Reder (2009). global case also needs eigenvalues weights matrix, solution numerical integration function, cases, timings quite acceptable. output comparable Saddlepoint approximation, inferences drawn chosen cut-analytical standard deviates calculated Normality. Li, Calder, Cressie (2007) take challenge Cliff Ord (1969, 31), try give statistic bounded fixed range. APLE measure intended approximate spatial dependence parameter simultaneous autoregressive model better Moran’s II, re-scales measure function eigenvalues spatial weights matrix. APLE requires use row standardised weights. order save time, use two internal functions spatialreg:::preAple spatialreg:::inAple, since definition spatial weights, eigenvalue calculations need made. notation using ::: operator says function named operator found namespace package named operator. APLE values repeat pattern already seen — variables, measured autocorrelation similar irrespective spatial weights definition, others, change definition binary general make difference.","code":"MoranI.boot <- function(var, i, ...) {   var <- var[i]   return(moran(x=var, ...)$I) } Nsim <- function(d, mle) {   n <- length(d)   rnorm(n, mle$mean, mle$sd) } f_bperm <- function(x, nsim, listw) {   boot(x, statistic=MoranI.boot, R=nsim, sim=\"permutation\", listw=listw,     n=length(x), S0=Szero(listw)) } f_bpara <- function(x, nsim, listw) {   boot(x, statistic=MoranI.boot, R=nsim, sim=\"parametric\", ran.gen=Nsim,     mle=list(mean=mean(x), sd=sd(x)), listw=listw, n=length(x),     S0=Szero(listw)) } nsim <- 4999 set.seed(1234) system.time({ MoranNb <- lapply(vars, function(x) f_bpara(x=eire_ge1[[x]], nsim=nsim, listw=nb_B)) MoranRb <- lapply(vars, function(x) f_bperm(x=eire_ge1[[x]], nsim=nsim, listw=nb_B)) Prop_unstdNb  <- lapply(vars, function(x) f_bpara(x=eire_ge1[[x]], nsim=nsim, listw=lw_unstand)) Prop_unstdRb  <- lapply(vars, function(x) f_bperm(x=eire_ge1[[x]], nsim=nsim, listw=lw_unstand)) Prop_stdNb  <- lapply(vars, function(x) f_bpara(x=eire_ge1[[x]], nsim=nsim, listw=lw_std)) Prop_stdRb  <- lapply(vars, function(x) f_bperm(x=eire_ge1[[x]], nsim=nsim, listw=lw_std)) }) res <- lapply(c(\"MoranNb\", \"MoranRb\", \"Prop_unstdNb\", \"Prop_unstdRb\", \"Prop_stdNb\", \"Prop_stdRb\"), function(x) sapply(get(x), function(y) (y$t0 -
