The phrase "aggregation index" is correct and usable in written English.
It can be used in contexts related to data analysis, statistics, or economics, where it refers to a measure that combines multiple data points into a single index.
Example: "The aggregation index provides a comprehensive overview of the market trends by consolidating various economic indicators."
Alternatives: "composite index" or "combined index".
The aggregation index was calculated from the ratio of the aggregate number after 30 min of rotation and the particle number at the beginning (Ai = (N0-N30)/N0).
The aggregation index was calculated by dividing the total GFP fluorescence in cell aggregates by the total GFP fluorescence in the well.
Canopy interception was correlated with gross precipitation, LAI, canopy density, biomass, mixed degree, uniform angle index, aggregation index.
Five regional types of rural housing land change were defined according to an aggregation index used to reflect landscape patterns.
Urban, slope, elevation and aggregation index of urban class contribute to the differences found in the NO3−-N concentrations.
Aggregation index (AI) values [100 · (1 − water dispersible clay / total clay)] were taken as an indicator of relative soil erodibility.
In contrast, increasing cohesion and aggregation index of agricultural and forested landscapes, respectively, results to an increase in surface runoff and sediment yield as baseflow decreases.
Soil erodibility was assessed by the use of an aggregation index (AI) computed from water dispersible clay (WDC) relative to total clay contents.
Core area percentage of landscape (CPLAND) and aggregation index (AI) were used to summarize fragmentation trends in species' geographic distributions, modeled using ecological niche modeling techniques.
In our conclusion, we suggest the use of effective mesh size (MESH), mean patch size (AREA_MN), landscape patch index (LPI), COHESION, and aggregation index (AI).
The results indicated that the variations in the erosion modulus were closely related to changes in the large patch index, patch cohesion index, modified Simpson's evenness index, and the aggregation index.
