At each level, model selection was initially via a hierarchical backward elimination procedure of factors at that level, with all included terms at lower levels of the hierarchy included in all models considered at higher levels of the hierarchy.
In the stratified analysis that included only women harboring high-risk HPV (Table 3), although many factors entered the initial multivariate model, the procedure of removing factors with less than 5% significance resulted in a final model with only one factor, current tobacco use.
First, a systematic optimization procedure of three factors involved in the enzymatic reaction was carried out using response surface methodology through a central composite design.
Also, eight subjects actually working in a nuclear power plant (NPP) tested the practical effectiveness of the proposed proactive alarm reduction method according to the procedure of human factors validation test under a dynamic simulation of a partial scope for an NPP.
The procedures of principal component factor analysis with varimax rotation and item-subtotal correlations were performed to assess the construct validity of the ATC-B (see Table 4).
The procedure of considering distance factor (Dist f ) in finding the next hop neighbor vehicle is presented in Fig. 5.
Procedure of partial cancellation factor (PCF) selection for the first stage of hard-decision partial parallel interference cancellation (PPIC) using GR employed by direct-sequence code-division multiple access (DS-CDMA) systems under multipath fading channel in the case of periodic code scenario is proposed.
For this reason, the estimation procedure of the scale factor is an operational research problem, which can be resolved through a specific software able to manage non-linear Likelihood functions directly, or through techniques allowing the use of non-specific software developed for the discrete choices analysis.
Kanematsu et al. [ 148] dealt with a rat bladder acellular matrix, as a model, incorporating bFGF by a reswelling procedure of the growth factor solution.
The statistical procedure of higher order factor analysis has been described and employed to reduce the number of domains on instruments such as the SF-36 and PDQ-39 in order to create a summary score.
