It is widely appreciated that many studies in psychological science suffer from low statistical power. One of the consequences analyzing underpowered with thresholds significance a high risk finding exaggerated effect size estimates, right or wrong direction. These inferential risks can be directly quantified terms Type M (magnitude) error and S (sign) error, which communicate design choices on...

Three main approaches on how audio signals can be used as input to a deep learning model are: extracting hand-crafted features from signals, mapping into appropriate images such spectrogram-like ones, and using directly raw signals. Among these approaches, the usage of represents compromise regarding bias enforced by processing (seen in features) computational demands signals). When any is inpu...

BACKGROUND Careful observation of the longitudinal course of bipolar disorders is pivotal to finding optimal treatments and improving outcome. A useful tool is the daily prospective Life-Chart Method, developed by the National Institute of Mental Health. However, it remains unclear whether the patient version is as valid as the clinician version. METHODS We compared the patient-rated version ...

Reconstruction of broken fragments is an extremely difficult task, mainly due to the high probability of missing pieces and the likelihood of erosion. This process is tedious and requires many hours to complete even for the experienced archaeologist. This paper describes some of the most successful fragment reconstruction algorithms and presents a new technique for reassembly. The technique rel...

Caspase-3 inhibitory activities of some 1, 2-benzisothiazol-3-one derivatives were modeled by quantitative structure-activity relationship (QSAR) using stepwise-multiple linear regression (SW-MLR) method. The built model was robust and predictive with correlation coefficient (R(2)) of 0.91 and 0.59 for training and test groups, respectively. The quality of the model was evaluated by leave-one o...

The Pearson correlation coefficient, ρ (rho), is a popular statistic for describing the strength of the relationship between two variables. It is the slope of the regression line between two variables when both variables have been standardized by subtracting their means and dividing by their standard deviations. The correlation ranges between plus and minus one. The population correlation ρ is ...
