The phrase "a subset of units" is correct and usable in written English.
It can be used when referring to a specific group or category that is part of a larger collection of units.
Example: "In our analysis, we focused on a subset of units that demonstrated the highest performance metrics."
Alternatives: "a portion of units" or "a segment of units".
Although all public health units received the report, only a subset of units was involved in the development of the report, while others were not.
As previously reported [ 29], a subset of units preferred for movement in a particular direction (direction sensitive; see Experimental Procedures).
A subset of units increased their spike rates as predicted (4/17 units, 23.5%), while other units had no significant change (17.7%), or decreased their firing rate significantly (58.8%).
The main goal of this study was to identify a subset of unit test case metrics: (1) providing useful information on the effort involved to write the code of JUnit test cases, (2) that are independent from each other, and (3) that are the less volatile.
In causal inference a matching algorithm assigns a subset of control units to each treated unit.
Pharmaceutical industry unit operations are a subset of the unit operations that are encountered in the chemical process industry.
The main goal of the study was to identify a subset of independent unit test case metrics: (1) providing useful information reflecting the effort involved in writing the code of unit test cases, and (2) that are the less volatile, i.e. the least affected by the style adopted by developers while writing the code of test cases.
The space ( Ω, d Ω ) is homeomorphic to the classical Cantor set treated as a subset of the unit interval with the usual topology.
Similarly, it can be argued that the multi-spacer set, considered as a subset of the unit interval, has the same fractal dimension as the Cantor middle-third excluded set — [16].
So this is a slight variant on a simple symbol shift, as the p-coordinate is a symbol shift to the right, while the q coordinate is, in effect, a symbol shift to the left.[17] One important feature of this dynamics is that it is measure preserving, so that if X is a subset of the unit square, μ(X) = μ(φ(X)).
We acknowledge that the units who did respond may potentially represent a biased subset of units.
