The phrase "a two steps model" is not correct in standard English; it should be "a two-step model." You can use it when referring to a model that consists of two distinct steps or phases in a process.
Example: "The research presents a two-step model for understanding consumer behavior."
Alternatives: "a two-phase model" or "a dual-step model."
On the other hand, Verma [23 26] introduced and studied a two step model for some systems of variational inequalities which were difference from the sense of Pang [18] and developed some iterative algorithms for approximating the solutions of these systems in Hilbert spaces base on the convergence analysis of a two step projection method.
Our exploration of a two step model selection procedure shows that identifying the true model is difficult.
"A Seven Step Model Of Planning Practice And Classic Readings From The Planning Field".
Specifically, a five step model is presented that transforms such applications into a parameterized graph model that, together with model abstraction and representations, can be the basis for solutions derived from graph and scheduling algorithms.
She then built a six step model for companies to follow.
For power saving they provided a three step model that consisted of optimization, reconfiguration and monitoring.
The most likely scenario accounting for the data available concerning Actinopterygian AR evolution is therefore a three step model: (i) ancestral duplication of a unique AR gene during the WGD event specific of teleost fishes.
18 This exponential increase contrasts with the existing literature, which presents the disease process as a three step model, in which all aneurysms larger than the surgical threshold size are assumed to have equal growth and rupture rates.
More recently, Elwyn (2012) presented a three step model for SDM in practice (Table 1) [ 18]: (1) choice talk, introducing the need for decision-making; (2) option talk, exploring the options and preferences; (3) decision talk, making the decision; and asked the experts to identify competencies necessary to perform these steps.
The proposed model, named AM2b, is based on the modification of the AM2 two step model initially proposed in [1].
