Blind computational reproduction of published statistical analyses with MerQur — Study 2: eleven further analysis families. Second round with MerQur 2.4.1, R and SAS (preregistration)

This document preregisters the second round of Study 2 of a blinded computational reproduction programme for MerQur, a free statistical software package. Twenty-two articles published in 2025-2026 with openly licensed raw data, two in each of eleven analysis families, are re-analysed, blind to the published results, by three independent analysts using MerQur 2.4.1 (frozen at code commit b35ff79da354f93fb2b0d64f9ed6778ff4eb3e62), R and SAS; every reported value is classified with a predefined decision tree. The document is self-contained: it reproduces the first-round preregistration (https://doi.org/10.5281/zenodo.23858471) with the second-round changes integrated. First-round results are not used. No second-round analysis had been run at the time of this deposit.
