Mary G. Lieberman’s research while affiliated with Florida Atlantic University and other places

... Serlin and Kaiser (1976) suggested removing items that have low weights derived from the first principal component of the intercorrelation matrix of items. Examination of the alpha of all possible subsets of items has also been suggested (Morris, 1978a(Morris, , 1978bLieberman, Morris, & Vásquez-Colina, 2023). The latter can be computationally intensive; with k items, alphas for 2 k -1 -k combination of items are necessary. ...

... Morris, Florida Atlantic University, Lieberman, and Florida Atlantic University [22] employed a multiple regression model to determine that attitudes were the primary determinant of an intention to wear seat belts in scenarios of safe driving, while norms were the primary determinant of behavior in hazardous driving situations. In order to examine this phenomenon, Fishman, Yang, and Mandell [23] carried out a series of three studies with the aim of altering the attitudes of participants regarding the significance of utilizing a seat belt while operating a vehicle. ...

... This then allows delivery of a statistical methods course, from beginning to advanced using only software that is local and familiar to the student. We offered this software in the height of the pandemic (Morris & Lieberman, 2021). We offer many extensions, our experiences, and student evaluations here. ...

... In order to assess symmetry and disagreement, Morris and Lieberman's (2018) method was applied. This method conducts the Cooper (1976) and Whitney (1978) inferential tests for polarity of sentiment which depend on the normal and t distributions respectively for larger samples, providing effect size estimates as well. ...

... Furthermore, we performed a detailed correlation analysis, employing cross-correlation to gauge the importance of features for classification: a relevant feature has a high correlation with the target variable but a low correlation with other features [30]. The analysis also shows the potential impact of multicollinearity on the classification of this dataset [31] by calculating the level of the features' mutual correlation. Lastly, cross-correlation has been Sensors 2025, 25, 1468 6 of 20 used to detect data overlap by showing the level of similarity between the time series from different classes. ...

... This study uses correlation coefficient > 0.80 to indicate collinearity and multicollinearity between independent variables as the sample number is small (Berry & Feldman, 1985). VIF more than 2 is also used to specify multicollinearity after multivariate analysis (Morris & Lieberman, 2012;Tabachnick & Fidell, 2007), particularly in PLS-SEM (see Chapter 7). ...

... Some studies have shown that adult adoptees are at higher risk of depression (Borders et al. 2000;Cubito and Brandon 2000), low selfesteem (Borders et al. 2000;Levy-Shiff 2001), substance abuse (Bohman and von Knorring 1979), personality disorders (Bohman and von Knorring 1979), alienation (Lieberman and Morris 2004), psychological distress ( Levy-Shiff 2001;Smyer et al. 1998), low educational achievement, and low IQ ( Teasdale and Owen 1986). Other studies have found no difference in substance abuse or criminality (Bohman and Sigvardsson 1990;Borders et al. 2000), life satisfaction ( Borders et al. 2000), or general psychological adjustment ( Collishaw et al. 1998;Feigelman 1997), or have found a better adjustment in adoptees for educational achievement, alcohol consumption, and affiliation, to give a few examples (Lieberman and Morris 2004;Smyer et al. 1998). ...

... The rule of thumb for assessing VIF value should be less than 10.00 while the threshold for bivariate correlation should not be more than 0.800 (Morris and Lieberman, 2015;Kalnins and Praitis Hill, 2025). The results revealed that the values are lower than the cutoff values and there is no serious multicollinearity issue in the data (see Figure 2). ...

... In this study, a crucial question we aimed to address is which features in resting-state EEG drive age prediction. Though not detrimental to the overall prediction accuracy (Mundfrom et al., 2018;Morris and Lieberman, 2018), including highly correlated features in a regression model -especially features extracted from neighboring electrodes or ROIs -would negatively impact the ability to accurately interpret the statistical importance of each independent variable (feature) (Farrar and Glauber, 1967;Kim, 2019). Here, we proposed a viable approach to circumvent this multicollinearity problem by evaluating feature importance at a cluster level using hierarchical clustering and Shapley Additive Explanations (SHAP) values (Fig. 3A). ...

With globalisation, humanity has entered a new era and individuals have faced brand new practices and regulations in the new world order that has become a global village (Barber, 2000;Kirkwood-Tucker, Morris, & Lieberman, 2010). As a result of increasing inequalities and changing balances with globalisation, countries have started to experience overpopulation, international migration, environmental degradation and so on, and with this, the relationships and socio-economic environments of individuals in their daily lives have also started to change (Drucker 1993;Kennedy 1993). ...
