Dear list members, Sorry for cross-posting.
I measured an index on 12 points within each of 3 cover types on 4 seasons. But the index was measured several times within hours, on different days and different months. I want to assess changes in the index among cover types and seasons. Is the following model parameterization appropriate in the lme4 package: mod_adi_01 <- lmer(ADI ~ Season*CoverType + (1 | Point) + (1 | Month) + (1 | Day) + (1 | Hour), data = df_01, REML = FALSE) Manuel -- *Manuel Spínola, Ph.D.* Instituto Internacional en Conservación y Manejo de Vida Silvestre Universidad Nacional Apartado 1350-3000 Heredia COSTA RICA mspin...@una.cr <mspin...@una.ac.cr> mspinol...@gmail.com Teléfono: (506) 8706 - 4662 Personal website: Lobito de río <https://sites.google.com/site/lobitoderio/> Institutional website: ICOMVIS <http://www.icomvis.una.ac.cr/> [[alternative HTML version deleted]] _______________________________________________ R-sig-ecology mailing list R-sig-ecology@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-ecology
