specific focus on the effects of supervisor support, resulting in the development of a research model of the transfer process. All components of the model were measured by means of questionnaires for former trainees and their supervisors, and stepwise regression analyses were carried out to examine the relationships in the model. Results indicate indirect relationships between supervisor support and transfer of training, by means of both trainees' motivation to transfer and the transfer climate. The indirect

* . Definition of correlation• Correlational research determines to what degree a relationship exists between 2 variables (or more variables). * 3. The nature of correlational research • Associational research: When the relationships among two or more variables are studied without any attempt to influence them. (The same as correlation and causal comparative research). • Experimental research: Differs from correlational research in that there’s manipulation of variables. * 4. The nature of

measured prior to the experiment. Other response variables included subjectively assessed somaticisation and a subject self-rating scale on performance during the talk. The subjects gave the talk twice each to adifferent audience, but in the analysis only the results of the first talk are presented -thus making this a between-groups design. The results show that post-talk PRCS is significantly and positively correlated to PRCS measured prior to the experiment in the case only of the positive

Poisson Extras References Linear regression GMM Efficient GMM Simple example The OLS model Consider the most common regression framework: y = Xβ + ε where we assume E (X ε) = 0 so our estimator β is unbiased. The usual approach is to define βOLS = (X X )−1 (X y ) that minimizes the sum of squared residuals (y − y )2 = and has an easy solution.
