The predictors are variables I suggest that will have an effect. I chose one predictor that came from literature. The sample size for the particular question of the dependent variable is 68 (entire sample size is 259). The correlations between variables exists but it not higher than ,500. Is it ok to use the backward-method in this case? | |
