The Trichotomous–Cubic Parametric Model (collectively abbreviated as “TRIMOD”) is a rigorous post hoc mathematical data analysis methodology designed to more accurately detail the outcomes of a statistically significant Tri–Squared Test. This particular statistical test is part two of the research published in the i-manager’s Journal on Mathematics entitled, “The Trichotomous–Cubed Test [Tri3]: An Advanced Statistical Data Analysis Methodology for Tri–Coordinate Meta–Analysis Using the Tri–Squared Test”. TRIMOD infuses the Tri–Cubed Test model with the Tri–Squared Test in a detailed sequential Tri–Coordinate series of x, y, and z planar vectors native to the Visualus Isometric Cuboid (Osler, 2010). A series of methodical mathematical calculation procedures are then conducted to yield the Tri–Cubic Parametric Model outcomes. This statistic further expands the field of post hoc trichotomous tests in terms of morphological and trend analysis analytics that are designed to provide in–depth insight into the Tri–Squared Test first introduced in the i-manager’s Journal on Mathematics.
