Sentence examples for procedures for variables from inspiring English sources

For this purpose, several procedures for variables selection, data pretreatments and unsupervised techniques were evaluated.

Although much has been written on developing better procedures for variable selection, there is little research on how it is practiced in actual studies.

The backward and the forward procedures for variable inclusion/exclusion within the logistic regression model determined pharyngeal localisation (P⩽0.001), higher T-stage (P⩽0.001) and CCNL1 copy number gain (P=0.049) as independent predictors for metastasis formation in HNSCC.

Later on, multivariate models were constructed with the backward stepwise procedure for variables significant at the 5% level.

To construct models we used the backward stepwise procedure for variables significant at the 5% level in the univariable analysis.

Later on, models were constructed with the backward stepwise procedure for variables significant at the 5% level.

Multivariate analysis was performed by logistic regression using a backward elimination procedure for variables not significantly associated with the Δage (Stomach Age-real age; P = 0.05) [ 22].

Using all the samples, the subgroups were compared according to the study variables listed in tables 1 and 2. Analysis of variance procedures for continuous variables and tests of independence for dichotomous or discrete variables were used.

This result suggests that as an exploratory procedure for variable selection, CART is able to detect important variables and reduce the number of variables for regression model.

Additionally, the BNN approach provides a nonparameteric procedure for variable selection while MANOVA relies on normality of errors for its testing procedure to be valid.
