Última Full Rank Rational Demand Systems AgEcon LaFrance, Jeffrey T.; Pope, Rulon D.. We extend the set of full rank nominal and deflated income demand systems to rational demand systems of any rank and present a unifying expression for the indirect preferences of all full rank demand models.

Ano: 2006 URL: http://purl.umn.edu/7152 Aggregation Theory for Incomplete Systems AgEcon LaFrance, Jeffrey T.; Beatty, Timothy K.M.; Pope, Rulon D.. Gorman's theory of demand is extended comprehensively to incomplete systems. The incomplete systems approach dramatically increases this class of models. The separate roles of symmetry and adding up are identified in the rank and the functional form of this class of models. We show that symmetry determines rank and the maximum rank is three. We show that adding up and 0o homogeneity determines the functional form and there is no functional form restriction for an incomplete system. We prove that every full rank system and reduced rank systems with a minimal level of degeneracy can be written as a polynomial in a single function of income. A complete set of closed form solutions for the indirect objective functions of this class of models is derived. A...

Ano: 2005 URL: http://purl.umn.edu/25033 Building Gorman's Nest AgEcon LaFrance, Jeffrey T.; Beatty, Timothy K.M.; Pope, Rulon D.. Gorman Engel curves are extended to incomplete systems. The roles of Slutsky symmetry and homogeneity/adding up are isolated in the rank and functional form restrictions for Gorman systems. Symmetry determines the rank condition. The maximum rank is three for incomplete and complete systems. Homogeneity/adding up determines the functional form restrictions in complete systems. There is no restriction on functional form in an incomplete system. Every full rank and minimal deficit reduced rank Gorman system has a representation as a polynomial in a single function of income. This generates a complete taxonomy of indirect preferences for Gorman systems. Using this taxonomy, we develop models of incomplete Gorman systems that nest rank and functional form and...

Ano: 2004 URL: http://purl.umn.edu/25027 Confidence intervals for rank statistics: Percentile slopes, differences, and ratios AgEcon Newson, Roger. I present a program, censlope, for calculating confidence intervals for generalized Theil–Sen median (and other percentile) slopes (and per-unit ratios) of Y with respect to X. The confidence intervals are robust to the possibility that the conditional population distributions of Y , given different values of X, differ in ways other than location, such as having unequal variances. censlope uses the program somersd and is part of the somersd package. censlope can therefore estimate confounder-adjusted percentile slopes, limited to comparisons within strata defined by values of confounders, or by values of a propensity score representing multiple confounders. Iterative numerical methods have been implemented in the Mata language, enabling efficient...

Ano: 2006 URL: http://purl.umn.edu/119241 On the Solutions to Full Rank Three Gorman Systems AgEcon LaFrance, Jeffrey T.. This letter closes a gap in the set of solutions for the full rank three systems of Gorman Engel curves and presents a unified expression for the indirect preferences in this case.

Ano: 2005 URL: http://purl.umn.edu/25048 Efeito da incorporação da covariância entre os efeitos direto e materno sobre a análise para a característica dias para ganhar 160 Kg Braz. J. Vet. Res. Anim. Sci. Malhado,Carlos Henrique Mendes; Lôbo,Raimundo Nonato Braga; Martins Filho,Raimundo; Facó,Olivardo; Azevedo,Danielle Maria Machado Ribeiro. O objetivo deste trabalho foi estudar o efeito da covariância entre os efeitos direto e materno sobre as estimativas dos parâmetros genéticos e nas predições dos valores genéticos, direto e materno, para a característica dias para ganhar 160 kg (D160) na fase pré-desmama. Os parâmetros e as predições dos valores genéticos foram estimados utilizando o aplicativo MTDFREML. O modelo 1 incluiu os efeitos genéticos direto e materno e de ambiente permanente, além do efeito fixo de grupo contemporâneo e da covariável idade da vaca ao parto, assumindo a covariância entre o efeito direto e materno (sigmaam<FONT FACE=Symbol>¹</FONT>0); o modelo 2, considerou os mesmos efeitos do modelo 1, mas a covariância entre os efeitos direto e materno foi...
