OBJECTIVE
To derive estimates of age-gender specific food availability, based on data collected at household level.
DESIGN
Two alternative modelling approaches are described leading to linear and non-linear optimisation, respectively. The idea of penalised least squares is used for estimation of model parameters. The effect of household characteristics can be incorporated into both modelling approaches.
SETTING
Household budget survey data from four European countries (Belgium, Greece, Norway and the United Kingdom), circa 1990.
目的
基于家庭层面收集的数据，得出按年龄和性别划分的特定食物可获得性估计值。
设计
描述了两种替代建模方法，分别导致线性和非线性优化。惩罚最小二乘法的思想用于估计模型参数。家庭特征的影响可纳入两种建模方法。
背景
约1990年来自四个欧洲国家（比利时、希腊、挪威和英国）的家庭预算调查数据。
