I have used the "minimum necessary model" approach over and over again: using a one-factor, one-industry model to explain the basic role of monopolistic competition in trade; assuming sector-specific labor rather than full Heckscher-Ohlin factor substitution to explain the effects of intraindustry trade; working with symmetric countries to assess the role of reciprocal dumping; and so on.
It is therefore called a one-factor-one-price elasticity.
Factor analysis of the GSE has consistently produced a one factor solution; that is, only one underlying dimension has been found [ 25].
The construct validity was confirmed with exploratory factor analysis and the results indicated a one factor solution which confirmed the instruments' one-dimensional internal structure [ 5].
In so doing, an item in a scale was assigned when its assignation was understandable from its content and it loaded on one factor (> = 0.50 on one factor, <0.40 on all the others).
In order to evaluate the model structure, we define three different experimental designs and according to Wu and Hamada (2009), each one is a one-factor-at-a-time.
A maximum-likelihood factor analysis with varimax rotation and the global non-parametric T11-statistic (Ponocny, 2001) that specifically tests for local stochastic independence were inspected to examine further whether a one-factor-solution fits the data and one-dimensionality can be warranted.
Factor analysis of the instrument suggested a one-factor model (only one factor with eigenvalues above 1 accounting for 22% of the variance).
Although the disease-specific HROQL (KDCS) and generic HRQOL (SF-36) components of the KDQOL-SF were highly correlated with one another, a one-factor model in which the KDCS and SF-36 represented overall HRQOL provided an unacceptable model fit, whereas a two-factor model fit the data reasonably well.
For instance, a score from a speaking test may have a one-on-one connection with a factor of speaking skills.
One political factor and one social factor seem to be in play in the Whitney's first retrospective of the artist since 1983 (at that time, the chief impetus was a vogue, begun in the seventies, for revisionist art history).
