lfebd3: Generation and Analysis of Confounded and Fractional Factorial Block Designs

Provides tools to generate and analyze 3-level linear factorial block designs, including complete factorial layouts, fractional factorial layouts, confounded factorial layouts, and design-characteristic summaries. The package includes utilities for recursive ternary construction, defining-contrast identification, alias/confounding summaries, incidence matrix construction, and design optimality diagnostics.The methodological framework follows foundational work on Gupta (1983) <doi:10.1111/j.2517-6161.1983.tb01253.x>. These methods assist in selecting, comparing, and studying factorial and fractional factorial block designs for large experimental situations.
