چکیده
χ value in the Chi-square distribution used to test for significant differences between three (or more) independent groups when using the Kruskall-Wallis non-parametric analysis of variance where the dependent variable is measured on an ordinal scale. p probability of making a type I decision error. z a value in the standard normal distribution that may be related directly to a probability value to determine statistical significance when using the Wilcoxon matched pairs signed ranks test to establish if there is a statistically significant difference between two related samples where the dependent variable is measured on an ordinal scale.

A conjugate gradient based method for Decision Neural Network training
Decision Neural Network is a new approach for solving multi-objective decision-making problems based on artificial neural networks. Using inaccurate evaluation data, network training has improved and the number of educational data sets has decreased. The available training method is based on the gradient decent method (BP). One of its limitations is related to its convergence speed. Therefore,...

The increasing complexity of decision making in a severely dynamic competitive environment of the universe has urged the wise managers to have relevant strategic plans for their firms. Strategy is not formulated from one criterion but from multiple criteria in environmental scanning, and often, considering all of them is not possible. A list of criteria utilizing Delphi was selected by consu...
متن کاملCompetency-based on-the-job training for aviation maintenance and inspection--a human factors approach.
More than 90% of the critical skills that an aviation maintenance technician uses are acquired through on-the-job training (OJT). Yet many aviation maintenance technicians rely on a 'degenerating buddy system', 'follow Joe around', or unstructured approach to OJT. Many aspects of the aviation maintenance environment point to the need for a structured OJT program, but perhaps the most significan...

1 This work was supported by Contract No. N61339-96-R-0046 with the Naval Air Warfare Center Training System Division. Abstract There is an opportunity to explore synergies between training and decision support in the Tactical Decision Making Under Stress (TADMUS) program. Decision making skill appears to involve a combination of recognitional and metacognitive elements. A model of decision mak...
