- Rail;

- Pipeline;
- Air;
- Unknown mode.

A model is a formalised expression of a theory or the causal situation which is regarded as having generated observed data. In statistical analysis the model is generally expressed in symbols, that is to say in a mathematical form, but diagrammatic models are also found. The word has recently become very popular and possibly somewhat over-worked.

A general population survey that provides detailed and nuanced information about how people with and without disabilities conduct their lives and the difficulties they encounter, regardless of any underlying health condition or impairment.

Uses data from passed edit records to regress the variable for which imputation is required on a set of predictor variables.

The construction of physical, conceptual or mathematical simulations of the real world. Models help to show relationships between processes (physical, economic or social) and may be used to predict the effects of changes in land use.

The pricing of identical products or models in consecutive periods to ensure that the measured price change cannot be affected by changes in quality. In other words, pricing to constant quantity. Price changes for perfectly matched products may be described as “pure” price changes.

Modified accrual accounting differs from accrual accounting in that physical assets are expensed at time of purchase.

Modified cash accounting differs from cash accounting in that it recognizes receipts and disbursements committed in the budget year and allows a specified period after year-end for payments of these to be recorded and reported.

This approach consisted of a core module carried out on a complete enumeration basis to provide key structural data, in conjunction with one or more sample-based census supplementary modules to provide more in-depth data.

Education programmes in which students may compose the content of their education in a flexible way by combining different courses or modules. Modular programmes thus often do not have clearly-defined sequencing.

A separate component of the agricultural census – a modular approach is used for the agricultural census, with core and supplementary modules.

A module done by the UNICEF and the Washington Group that includes questionnaire list that covers children between 2 and 17 years of age and assesses functional difficulties in different domains including hearing, vision, communication/comprehension, learning, mobility and emotions.

An unlined underground drainage channel, formed by pulling a solid object, usually a solid cylinder with a wedge-shaped point at one end, through the soil at the proper slope and depth. This system is less expensive then digging a trench.

The gap between rich and poor farmers, between research priorities and needs, and between technology development and actual technology transfer, is widening.

Class of animals with soft bodies (and often hard shells), e.g. oysters, mussels, cuttlefish, snails, slugs.

Accounts expressed in monetary terms, using only currency as the unit of measure. Monetary is to be taken as synonymous with ‘economic value’ as understood in economic theory.

Are compiled by Central Banks on the basis of surveys of monetary and financial institutions; they measure the amount of money circulating in an economy, and usually presented as end-of-month national currency stock series.
