fetal_covid_data

The data were recorded via 4D ultrasound scans from 40 fetuses (20 before Covid and 20 during Covid) at 32 weeks gestation,
and consist of the number of movements each fetus carries out in relation to the recordable scan length.

datasets

Fitting multivariate response models with random effects on one or two levels; whereby the (one-dimensional) random effect represents a latent variable approximating the multivariate space of outcomes, after possible adjustment for covariates. The method is particularly useful for multivariate, highly correlated outcome variables with unobserved heterogeneities. Applications include regression with multivariate responses, as well as multivariate clustering or ranking problems. See Zhang and Einbeck (2024) <doi:10.1007/s42519-023-00357-0>.
