The phrase "a unitary model" is correct and usable in written English.
It can be used in contexts discussing theories, frameworks, or systems that are integrated or singular in nature.
Example: "The researchers proposed a unitary model to explain the complex interactions between various environmental factors."
Alternatives: "a unified model" or "a singular model".
A unitary model of schizophrenia.
A unitary model of the BFNE-II resulted in excellent confirmatory factor analysis fit indices.
Our review of the evidence supports neither a unitary model of lateral frontal function nor a unidimensional abstraction gradient.
The search for a unitary model of sleep-memory relationships seems still far from accomplished, despite the huge body of data produced in the latest twenty years.
Starting from a critical review of the state of the art, a unitary model of the 3-D atmospheric turbulence was proposed where all parameters are defined by first- and second-order statistical moments derived from a wide selection of experimental measurements.
Second, to examine the factor structure of the TOEFL iBT test, we investigated whether a unitary model fit the data (see Fig. 2).

Two different finite element models are built: (1) a unitary cell model in which the localization is favoured by a sinusoidal geometrical perturbation and (2) a plate with constant cross section which allows to assess the collective behaviour of multiple necks.
However, a unitary factor model and a higher-order factor model are similar in that the four skills of reading, listening, writing, and speaking are subsumed in an underlying, higher-order ability.
By imposing more structure on the general model, we can derive testable implications on observed demand for public goods and labor supply that allow testing the model against the standard unitary model where a couple behaves as a single decision maker.
The proposed approach is a step forward towards the formulation of a unitary probabilistic model of the wind-excited response of structures, comprehensive of model errors, parameter uncertainties and parameter randomness.
