"The half of the orchestra behind the screen was looking up at a giant projection of Lorin, and half of the orchestra was seeing him conduct backwards," said Eric Latzky, a spokesman for the orchestra.
The full model and null model performed poorly in explaining the variance in the data, and therefore, model selection was conducted using backwards stepwise elimination of predictor variables through examination of R values, AIC scores, QQ and residual plots to identify the best model for the data.
A multivariable analysis was then conducted using a backwards stepwise logistic regression to analyse these factors simultaneously and to consider potential interactions.
Multiple logistic regression using survey commands was conducted using stepwise backwards elimination of variables in order to determine the factors significantly associated with the outcome of breastfeeding indicators.
Logistic regression was conducted using stepwise backwards generalized linear latent and mixed models (gllamm) [ 14] method in order to determine the factors significantly associated with the rate of EBF.
Logistic regression modelling, that included all practitioner and practice characteristics variables, was conducted using a backwards stepwise method of elimination using a likelihood ratio test, to parsimoniously predict referral to naturopaths.
Gleason Score, age, year of diagnosis, T stage, and pretreatment PSA were included into the multivariable logistic regression model, as these factors had been decided a priori to affect a clinician's decision to place a patient on ADT, and variable selection was conducted using a backwards stepwise procedure.
We also conducted forward selection and backwards elimination stepwise regression using a cutoff value of p = 0.10 in both directions to further inform our final model selection.
At all phases translation has been conducted using two forward, one backwards translation methodology, where two independent forward translations are harmonized and then back-translated to confirm accuracy of the translation.
A monitored backwards stepwise approach was conducted, and models were assessed for convergence.
