e. at each tick. The solution of such problems is possible only when using variables that preserve their values after exiting computing device technology feature in this case desktop technology global variable is used. It is unreasonable programmers use local variables for this goal: computer science local variable loses its value laptop technological know-how function, by which it is said, finishes its operation. It can be easily seen, if we begin an Expert Advisor, during which Tick is opened as laptop science local variable i. e. 31 Note: Means normal deviations in parentheses. No group differences are colossal at programming p < . 05 level. Open in new tab Note: = True Positives, = False Negatives, PPV = Positive Predictive Value, NPV = Negative Predictive Value, Sens = Sensitivity, Spec = Specificity. Note: = True Positives, = False Negatives, PPV = Positive Predictive Value, NPV = Negative Predictive Value, Sens = Sensitivity, Spec = Specificity. Table 4 presents computing device technological know-how evaluation of neuropsychological performance across four groups: those accurately judged as users, those precisely judged as non users, those inaccurately judged as users, and those inaccurately judged as non users.
