# Generate Data
mydata <- rblimp_sim(
    c(
        'x ~ normal(0, 1)',
        'y ~ normal(0, 1)',
        'group = uniform(0, 1) < 0.5'
    ),
    n = 1000,
    seed = 10972
)

# Nonsensical model
mdl <- rblimp_fcs(
    c('x', 'y'),
    mydata,
    seed = 3927,
    nimps = 2,
) |> by_group('group')

# Analyze each imputation
results <- with(mdl, lm(y ~ x))
# use `mitml` package to pool results
