H4 The relationship between Estate Factors and FFB Processing is moderated with Logistics Efficiency

Process procedure version 3.3 by Andrew F. Haze, 2018 Model 1 for moderation (Fig. 4.6, page 257)

Moderator variable affects the relationship between two variables as such that the impact of the predictor on the criterion varies according to the level or?value of the moderator (Holmbeck, 1997).

Appendix 28????????Y????FFBPROC??????????????????? Dependent

?????????????????????????????X????ESTATEFAC Independent

?????????????????????????????W???LOGEFF??????????????????????Moderator

Level of confidence 95.0000, ‘W’ values in conditional tables are the mean and +/- SD from the mean.

Variables mean centered prior to analysis LOGEFF and ESTATEFAC (to reduce multicollinearity and make interpretation easier)

?????????????????????????????

Mean Square Error measures the average of the squares of the errors

(very high MSE for test and validation)

R(sq)chng which is just the improvement in R(sq) when the second predictor is added. R(sq)chng is tested with F-statistics. Significant Fchng improved the prediction.

Since R(sq)chng is 0.00, F < 3.95 and further more significance probability P is 0.59 non-significant, it?mean the effect does not exist.

Conditional effects of the focal predictor at values of the moderator

?0.33????? -0.35?????0.07??????-5.39????? 0.00?????? -0.48????? -0.22

The b-value for LOGEFF, associated std errors adjusted for heteroscedasticity, each b is compared to zero using a t-test which is computed beta divided by its std error, the confidence interval for the b is also produced.

Since the confidence interval is negative, the true effect size is same as ‘no effect ‘and there is no moderation.??????

Since effect size none, it can safely assume the non-significance means a real lack of effect (McShane & B?ckenholt, 2016).

Data for visualizing the conditional effect of the focal predictor????

A simple slope is defined as the regression of the outcome ‘y’ on the predictor ‘x’ at a specific value of the moderator ‘w’

To understand potential interaction effects, since the lines are parallel there is no interaction (Fig. 4.7, page 261)

Therefore, hypothesis H4, The relationship between Estate Factors and EEB Processing is moderated with Logistics Efficiency is not supported.

Note: Hypothesis H4 was tested because we know it will be supported. The negative result above was due to some factors selected were unable to interact in this moderation model. Remove these factors to repeat the test and you will find hypothesis H4 is supported.

FFB Processing moderates Estate Factors to FFB Processing is not supported, Recap of this presentation next slide 27-27
