## CRAN-purpose small example
x = rnorm(10)
var1.chisq(x, alternative="g") ## Ha : var(x) >= 1
var1.chisq(x, alternative="l") ## Ha : var(x) <= 1
var1.chisq(x, alternative="t") ## Ha : var(x) =/=1
# \donttest{
## empirical Type 1 error
niter = 1000
counter = rep(0,niter) # record p-values
for (i in 1:niter){
x = rnorm(50) # sample x from N(0,1)
counter[i] = ifelse(var1.chisq(x,var0=1)$p.value < 0.05, 1, 0)
