%description
Addressing a central challenge encountered in Mendelian randomization (MR)
studies, where MR primarily focuses on discerning the effects of
individual exposures on specific outcomes and establishes causal links
between them. Using a network-based methodology, the intricacy involving
interdependent outcomes due to numerous factors has been tackled through
this routine. Based on Ni et al. (2018) <doi:10.1214/17-BA1087>, 'MR.RGM'
extends to a broader exploration of the causal landscape by leveraging on
network structures and involves the construction of causal graphs that
capture interactions between response variables and consequently between
responses and instrument variables. 'MR.RGM' facilitates the navigation of
various data availability scenarios effectively by accommodating three
input formats, i.e., individual-level data and two types of summary-level
data. In the process, causal effects, adjacency matrices, and other
essential parameters of the complex biological networks, are estimated.
Besides, 'MR.RGM' provides uncertainty quantification for specific network
structures among response variables.
