Group Comparison: Sequenzo and TraMineR Mapping
This page maps Sequenzo group-comparison functions to their closest TraMineRextras counterparts.
What This Section Covers
This section focuses on predefined two-group sequence comparison using LRT/BIC logic.
For TraMineR users, this matches the TraMineRextras::seqCompare() workflow (overall test plus LRT-only and BIC-only wrappers; R exposes these as seqCompare, seqLRT, and seqBIC in TraMineRextras).
Mapping Table
| Sequenzo function | R counterpart | Notes |
|---|---|---|
conceptual-guide | TraMineRextras::seqCompare() methodological framework | Conceptual explanation of one-group vs two-group comparison and interpretation of LRT/BIC evidence. |
get_group_differences | TraMineRextras::seqCompare() | Main overall two-group comparison interface; returns LRT/BIC outputs depending on stat. |
get_lrt_test | TraMineRextras::seqLRT() | LRT-focused wrapper built on the same overall comparison engine. |
get_bic_test | TraMineRextras::seqBIC() | BIC-focused wrapper built on the same overall comparison engine. |
