Component selection (SNMU)

NoClustering

Component selection and population subgrouping (SNMU + k-means clustering)

Kmeans

Component selection followed by K-Means clustering of individuals based on their component exposure. K-means classifies individuals in multiple groups (i.e., clusters), such that individuals within the same cluster are as similar as possible (i.e., high intra-class similarity), whereas individuals from different clusters are as dissimilar as possible (i.e., low inter-class similarity). In k-means clustering, each cluster is represented by its center (i.e, centroid) which corresponds to the mean of points assigned to the cluster.

Component selection and population subgrouping (SNMU + hierarchical clustering)

Hierarchical

Component selection followed by hierarchical (Ward’s) clustering of individuals based on their component exposure. Hierachical clustering builds a hierarchy from the bottom-up, and doesn’t require to specify the number of clusters beforehand. Hierarchical clustering produces a tree-based representation of the observations known as a dendrogram.

Exposure approach types

Accepted Exposure approach types. Controlled terminology.

Table 410 Unit definition for Exposure approach types.
Name Short name Aliases Description

Risk based (RPFs)

Risk based (RPFs)

Exposures are multiplied by the RPF and thus exposures to different substances are on the same and comparable scale.

Standardised

Standardised

All substances are standardised to equal variance (selection of the components will work on patterns of correlation only).

Unstandardised (RPFs = 1)

ExposuresUW

Exposures as such are taken (unstandardised). This is equivalent to RPFs equal to 1. Thus exposures to different substances are not on the same and comparable scale anymore.

Testing method types

Accepted xxx types. Controlled terminology.

Table 461 Unit definition for Testing method types.
Name Short name Aliases Description

Backward

Backward

Backward selection starts with selecting a model with a function of the highest degree. Then, the degree of the function is decreased by one and the model is tested again. This process is repeated until decreasing the degree does not improve the model fit anymore.

Forward

Forward

Forward selections starts with selecting a model with a function of the lowest degree. Then, the degree of the function is increased by one and the model is tested again. This process is repeated until increasing the degree does not improve the model fit anymore.

Name Short name Aliases Description

No correlation

NoCorrelation

The unit residue values for unit portions (consumption amount/unitweight) are randomly drawn, explicitly ignoring any correlation between unit residues.

Full correlation

FullCorrelation

The unit residue values for unit portions (consumption amount/unitweight) are randomly drawn, explicitly introducing correlation between unit residues, e.g. high (small) values occur more frequently together.

Unit variability model types

Accepted Unit variability model types. Controlled terminology.

Table 466 Unit definition for Unit variability model types.
Name Short name Aliases Description

Beta distribution

Beta distribution

Requires knowledge of the number of units in a composite sample, and of the variability between units (realistic or conservative estimates). Under the beta model, the simulated unit values are drawn from a bounded distribution on the interval.

Lognormal distribution

Lognormal distribution

Requires only knowledge of the variability between units (realistic or conservative estimates). The lognormal distribution is considered as an appropriate model for many empirical positive concentration distributions (unbounded distribution).

Bernoulli distribution

Bernoulli distribution

Requires only knowledge of the number of units in a composite sample (results are always conservative). The bernoulli model is a limiting case of the beta model, which can be used if no information on unit variability is available, but only the number of units in a composite sample is known.
