Agglomerative hierarchical clustering
Agglomerative hierarchical clustering is a bottom-up clustering method that starts with each data point as its own cluster and merges the closest pairs, yielding a dendrogram.
Agglutination
Agglutination is the linguistic morphology in which words string together segmentable morphemes, each expressing one grammatical function, as in Turkish and Hungarian; contrasted with fusional, isolating, and polysynthetic types and measured by Greenberg's agglutination index.
Agglutination (biology)
Agglutination (biology): clumping of cells, bacteria, or latex particles by specific antibody; basis of blood typing (Landsteiner, ABO) and serodiagnostic tests such as DAT, MAT, latex agglutination, and IHA.
Agglutination test
An agglutination test is a diagnostic immunoassay in which antibodies cross-link antigen-bearing cells or particles into clumps visible by eye, used to detect antigens or antibodies in blood, urine, or saliva.
Agglutinative language
Agglutinative language: a morphological type where words concatenate clearly segmentable morphemes, each carrying one meaning (Turkish ev-ler-im-de, Finnish, Tamil, Korean, Japanese). Distinct from fusional, isolating, polysynthetic types.
Aggradation
Aggradation is the raising of a land surface, most often a river bed or floodplain, through net sediment deposition, occurring when sediment supply exceeds a river's transport capacity.
Aggregate behavior
Aggregate behavior in macroeconomics is the behavior of economy-wide quantities such as output, consumption, employment, and the price level, which need not resemble the summed behavior of individual households and firms.
Aggregate demand
Aggregate demand, also called final demand, is the total planned spending on an economy's goods and services, written as C + I + G + (X − M).
Aggregate production function
The aggregate production function is a mathematical relationship expressing an economy's total output as a function of total capital and labor, underlying growth accounting and the Solow growth model.
Aggregate supply
Aggregate supply is the total output, measured as real GDP, that firms produce and sell at each price level, paired with aggregate demand in macroeconomic analysis.

Aggregation (cloud physics)
Aggregation in cloud physics is the process by which ice crystals collide and stick together inside clouds, forming large irregular snowflakes; it is a key process in precipitation growth.
