A minor update that introduces a number of additional features.
mediate_tsls() that conducts mediation analysis using an instrumental variable estimatormediate(), the boot = TRUE option now makes use of the boot() function in the boot package to implement nonparametric Bayesian bootstrap. Users may also pass arguments to the boot() function in the boot package e.g. parallel or ncpus.mediate(), add a use_speed option to re-fit lm and glm models using functions from the speedglm package when nonparametric bootstrap is used.system.file() function from base is written over by other packages e.g. pkgload.
