The phrase "a variable which describes" is correct and usable in written English.
It can be used in contexts related to programming, mathematics, or data analysis when explaining the role of a variable in a given situation.
Example: "In our study, we identified a variable which describes the relationship between temperature and plant growth."
Alternatives: "a variable that represents" or "a variable that indicates".
We model the uncertain demand as a hybrid variable which describes the quantities with fuzziness and randomness.
where D n (t) is a random variable which describes the number of packets that are successfully received by node n during [0,t].
where w(t) and k(t) are zero-mean Gaussian distributed processes, b t) is a {0,1}-random variable which describes the state of the channel and t is the time index.
Let X be a distributed ℳ O random variable which describes the lifetime relative to each individual in the population with a vector of p-covariates z= z1,…,z p )⊤, where ⊤ denotes the transposition operator.
They include gender, age (in categories), socio-professional status, holding of a driving license, and a combination of variables which describe the role of the individual (head, spouse or child) and the household structure (single or couple; with child under 12 or not; zero, one or two workers).
These models are based on a number of predictor variables which describe habitat variation measured at several farms in Oxfordshire, UK.
We opted to use the index of relative disadvantage, which is a composite indicator summarising multiple Census variables which describe socioeconomic circumstances.
The model is formulated in the frequency domain and leads to relatively simple closed-form solutions for the variables which describe the dynamic interaction.
We generated more than 78 flow variables, which describe the frequency, magnitude, duration, rate of change, and timing of flow events.
However, on the other hand, displacement variables, which describe the kinematics of the shell structures, are defined using Equivalent Single Layer (ESL), Zig-Zag (ZZ) and LW shell theories.
