The models included Helmert
contrasts and univariate tests with Bonferroni post hoc comparisons performed after obtaining a significant model effect.
Normal gravity values on the reference ellipsoid are obtained from the Helmert
2]), physical activity (regularly > 2 hr/week, regularly ~ 1 hr/week, irregular ~ 1 hr/week, nearly no sport activities, based on a combination of sport activities during summer and winter), and socioeconomic status [SES; quintiles of the Helmert
and Shea 1994), based on school education, professional status, family income].

Researchers used a Helmert
contrast, an orthogonal contrast that allows for the comparison of the control group with K-PALS Levels 1 and 2 combined as well as K-PALS Level 1 with Level 2, to address the specific research questions.
At the same time, in the paper entitled "A Statistical Analysis of Consumer Attitudes to Hospitality Services Abroad" (Saierli, Vasilescu & Pater, 2010), we have used a Helmert

These coordinates were transformed into the new European terrestrial reference system ETRS89 by using a spatial 7-parameter Helmert
21) For the system GMM estimation and IRFs one observation is lost with the Helmert
transformation, where the available observations for estimation are between 1963 and 2005 in the bivariate VAR and between 1971 and 2005 in the multivariate VAR.
As he works he covers projection spaces and vector space theory, the least squares theory, distribution theory, Helmert
matrices and orthogonal relationships, diagnostics and robustness in residual analysis, models that include variance components, likelihood approaches, and incorrelated residuals formed from the linear model.
Apart from Christensen and Suzuki, other foreign-born, British-trained makers in the Birmingham collection include the Germans Andreas Fabian and Simone ten Hompel and the New Zealander Helmert
