The meta-analysis of coefficient alpha across many studies is becoming more common in psychology by a methodology labeled reliability generalization. Existing reliability generalization studies have not used the sampling distribution of coefficient alpha for precision weighting and other common meta-analytic procedures. A framework is provided for a statistically grounded meta-analysis of coeff...

• In this lesson, we will learn how to measure the coefficient of correlation for two sets of ranking. • The coefficient of correlation, r, measures the strength of association or correlation between two sets of data that can be measured. Sometimes, the data is not measurable but can only be ordered, as in ranking. • For example, two students can be asked to rank toast, cereals, and dim sum in ...

This paper describes the principle of MFCC feature extraction and the knowledge of human auditory masking effect in order to introduce a modified-MFCC feature extraction that can improve the robustness of speech recognition systems.

1. The experiments of Madsen and Watabiki on the effect of temperature on the phagocytosis of bacteria are discussed and a new analysis of their curves is given, showing that the rate of phagocytosis is very nearly a logarithmic function of the temperature from 0 degrees to 35 degrees C.; i.e., Q(10) is constant over that range and is equal to 2.0. 2. New experiments are reported on the effect ...

Some subclasses of analytic functions f(z) in the open unit disk U are introduced. In the present paper, Some interesting sufficient conditions, including coefficient inequalities related close-to-convex functions f(z) of order α with respect to a fixed starlike function g(z) and strongly starlike functions f(z) of order μ in U, are discussed. Several special cases and consequences of these coe...

Improving the detection of relevant variables using a new bivariate measure could importantly impact variable selection and large network inference methods. In this paper, we propose a new statistical coefficient that we call the rank minrelation coefficient. We define a minrelation of X to Y (or equivalently a majrelation of Y to X) as a measure that estimate p(X ≤ Y ) when X and Y are continu...

زمینه و هدف: خلق مثبت انعطاف‌پذیری شناختی از عوامل تقویت کننده خلاقیت شناخته‌ می‌شوند. مطالعه حاضر با این فرض که احتمالاً اثرگذاری بر موجب ارتقا می‌شود، مهم را در بازه سنی 8 تا 12 سال بررسی کرده است. روش پژوهش: جامعة پژوهش شامل کلیه دانش آموزان دختر ۱۲ ساله مناطق 4 ۸ شهر تهران بودند. جامعه 60 نفر دو گروه ۱۰ (76/0±80/8) (76/0±20/11) به نمونه‌گیری دسترس انتخاب شد. پس جایگذاری تصادفی افراد گروه‌های...
