The phrase "a function of productivity" is correct and usable in written English.
It can be used when discussing how one variable or factor is dependent on or influenced by productivity levels.
Example: "The success of the project is largely a function of productivity, as higher output leads to better results."
Alternatives: "a result of productivity" or "dependent on productivity".
For this purpose, we estimate a regression model of occupational rates as a function of average productivity, controlling for unemployment rates and for time and region fixed effects, using the AACC data.
This study aims at developing a model-based method for optimization of sugarcane straw recovery costs and internal rate of return (IRR), as a function of sugarcane productivity, straw recovery fractions and transport distances considering two recovery systems: integral harvesting (IS) and baling system (BS).
The logging cost is a function of harvested volume, productivity of felling, and on-site transport.
This circumstance led Galbally and Kirstine (2002) to simulate global methanol emissions as a function of net primary productivity (NPP) that consists of pectin and the fraction thereof which is demethylated during growth, an approach which later has been adopted by others (Jacob et al., 2005; Millet et al., 2008).
This was most likely a function of differences in site productivity (Table 1) and, as a result, vegetation occurrence.
To the best of our knowledge, we have demonstrated for the first time the possibility of predicting H2aq and its effect on the fermentation in a laboratory-scale bioreactor as a function of stripping rate and productivity using the derived model.
To show the difference between the association of depression and productivity between the two studies, regression slopes of productivity as a function of BDI scores for the two studies were compared.
The practicum was tied together by a general research question (Are spatial patterns of Lake Ontario productivity a function of distance from the shoreline?), and a guided inquiry approach was used to help students frame testable hypotheses to address this question.
We tested whether remaining differences between predictions and actual data were related to variation in site productivity (a function of moisture availability as influenced by soil and landscape factors not modelled).
Now researchers have developed a model to estimate future undernutrition attributable to climate change as a function of its impact on crop productivity [ EHP 119(12):1817–1823; Lloyd et al.].
