Estimates average treatment effects at the cutoff based on sharp 
    regression discontinuity designs (RDD) and multiple imputation regression 
    discontinuity designs (MIRDD). It provides diagnostic tools for RDD by 
    comparing results with those from MIRDD, as proposed in Takahashi (2023) 
    <doi:10.1080/03610918.2021.1960374>. The package includes datasets from
    Takahashi (2023) and Takahashi (2026) <doi:10.1016/j.softx.2026.102707>.

Fitting recurrent events survival models for
    left-censored data with multiple imputation of the number of previous episodes.

Estimates random effect latent measurement models, wherein the loadings, residual variances, intercepts, latent means, and latent variances all vary across groups. The random effect variances of the measurement parameters are then modeled using a hierarchical inclusion model, wherein the inclusion of the variances (i.e., whether it is effectively zero or non-zero) is informed by similar parameters (of the same type, or of the same item). This additional hierarchical structure allows the evidence in favor of partial invariance to accumulate more quickly, and yields more certain decisions about measurement invariance.

Test for overall association between microbiome composition data 
  and phenotypes via phylogenetic kernels. The phenotype can be univariate 
  continuous or binary (Zhao et al. (2015) <doi:10.1016/j.ajhg.2015.04.003>), 
  survival outcomes (Plantinga et al. (2017) <doi:10.1186/s40168-017-0239-9>), 
  multivariate (Zhan et al. (2017) <doi:10.1002/gepi.22030>) and 
  structured phenotypes (Zhan et al. (2017) <doi:10.1111/biom.12684>). 
  The package can also use robust regression (unpublished work) and 
  integrated quantile regression (Wang et al. (2021) <doi:10.1093/bioinformatics/btab668>). 
  In each case, the microbiome community effect is modeled nonparametrically 
  through a kernel function, which can incorporate phylogenetic tree information.
