However, the validity of these formulas has been verified for only the limited variables considered in the experimental program.
Furthermore, only limited variables could be included in the multivariate analysis.
The Health Locus of Control, Self-Regulatory model, TPB and TTM all had the weakness that they tended to originate from a singular viewpoint which results in limited integration of the sources of influence, and thus they were able to account for limited variability in the dependent variable.
For the certainties and limited variables that govern the game of the chess and make it itself simply fail to obtain in the less neatly-ordered spheres of politics and society.
These are settings with similar speeds and limited variables.
Main study limitations include the possibility of helmet use reporting error and limited socioeconomic variables in YRBS datasets.
Due to the limited physiological variables in our analyses, we were unable to analyze the effect of Tai Chi on physiological effects.
Regression models included both GD and PD because of the limited sample size of PDs, their limited variability in responses to the case scenario, and their limited variability in responses to many explanatory variables.
Other models include combining ongoing, smaller studies to provide more immediate answers at potentially lower costs (2, 3), but existing studies are often limited and variable in the diversity of populations, exposures, and diseases ascertained; standardization of methods; and adequacy of existing consent and data access (4, 5).
For instance, an experiment deliberately takes away from the full complexity of a phenomenon, attending to a limited number of variables in a controlled environment (Yin 2013).
