The stochastic models were a model in which yearly correlations among parameters were retained, a model in which parameters were uncorrelated, and a model in which parameters were derived from log-normal distribution.
As this variable was a very strong determinant, the result of which potential tasks were not retained, a model was explored (model B) without the number of working hours.
Further item reduction occurred through step-wise regression by retaining a model suitable for minimizing the number of items and for maximizing the variance explained in comparison with the variance exhibited by the longer instruments.
To retain a parsimonious model given the sample size, n = 19, we did not include time in this model.
Furthermore, in order to retain a final model, a two-by-two interaction terms were checked for variables that remained statistically significant in the pre-final model.
Amazon wants to retain a similar model for e-books so it can lower prices and offer features like a lending-library for customers of "Prime", its quick-delivery service.
The choice to retain a mixed model of online learning and face-to-face instruction was made because audience feedback valued the opportunity for networking and one-on-one instruction on difficult complex informatic topics.
To understand why many students construct and retain a mental model in which chemical bonds contain energy that is then released as bonds break, we must look at the collective history of how this idea became so prevalent.
The ability of higher vertebrate embryos to retain a regulative model of development until such a late stage strongly suggests that localisation of maternally inherited determinants is not an essential component of the mechanisms specifying embryo polarity (Stern and Downs, 2012).
In the present study we are keen to retain a structural model for ERVs and therefore reject the use of repeat masking tools that are designed to detect repetitive nucleotide sequences, that may well be fragmented, rather than accurately count individual proviruses.
