Analysing the Effect of Decoupling on Agricultural Production: Evidence from Irish Dairy Farms using the Olley and Pakes Approach
Kazukauskas, Andrius; Newman, Carol F.; Thorne, Fiona S. - In: Journal of International Agricultural Trade and Development 59 (2010) 3
maximization objectives become profit maximizing objectives. In this paper we explore the impact of decoupling on the productivity … of Irish dairy farms using a modified version of Olley and Pakes methodology for productivity estimation. We isolate the … effect of decoupling on productivity by controlling for other policy changes that have occurred alongside decoupling. We also …

Identification of local multivariate outliers
Filzmoser, Peter; Ruiz-Gazen, Anne; Thomas-Agnan, Christine - In: Statistical Papers 55 (2014) 1, pp. 29-47
The Mahalanobis distance between pairs of multivariate observations is used as a measure of similarity between the observations. The theoretical distribution is derived, and the result is used for judging on the degree of isolation of an observation. In case of spatially dependent data where...

Robustness and sensitivity of conjoint analysis versus multiple linear regression analysis
Karakaya, Fahri; Awasthi, Abhrawashyu - In: International Journal of Data Analysis Techniques and … 6 (2014) 2, pp. 121-136
This study compares the robustness of conjoint analysis versus multiple linear regression when using orthogonal data. The explained variance (R²) by four independent variables was utilised to test the robustness of the regression analysis while Pearson's R and Kendall's tau were used for...

The maximum asymptotic bias of outlier identifiers
Becker, Claudia; Gather, Ursula - Institut für Wirtschafts- und Sozialstatistik, … - 1998
In their paper, Davies and Gather (1993) formalized the task of outlier identification, considering also certain performance criteria for outlier identifiers. One of those Criteria, the maximum asymptotic bias, is carried over here to multivariate outlier identifiers. We show how this term...

Breakdown and groups
Davies, P. Laurie; Gather, U. - Institut für Wirtschafts- und Sozialstatistik, … - 2002
The concept of breakdown point was introduced by Hodges (1967) and Hampel (1968, 1971) and still plays an important though at times a controversial role in robust statistics. It has proved most successful in the context of location, scale and regression problems. In this paper we argue that this...
