The identification problem is a well-known issue in latent variable modeling from both a structural equation modeling and item response theory perspective and refers to the fact that the location and scale of a latent variable is, by definition, arbitrary, whereas with observed data, the location...
delegated risk-taking. We formally test for the mediation following the three-step procedure suggested in Baron and Kenny (1986). In the first step, we test whether the average FEEDBACK significantly differs between the two treatment conditions and find that this is the case (ROI absentvs.ROI ...

clinical variable selection and model training. Univariate logistic regression was utilized to assess the correlation between clinical factors and outcome variable pCR. Among clinical factors (age, menopause status, clinical T stage, clinical N stage, clinical M stage, ER status, PR status and HER2 ...
Student's t-test (or Mann-Whitney U-test according to the frequency distribution of the variable) will be used to compare the means (or the distribution) of the two study arms for continuous variables. Chi-square test or chi-square for trend will be used to compare proportions for ...
Clinician global assessments (CGAs), including clinician global impressions and clinical global impressions of change, are assessments based on a clinician’s overall judgment(s) of 1) the patient’s total health status or 2) an aspect(s) of their health status for which the variable(s) assess...
Regarding the drugs, for group 1, the mean and standard deviation of the indicator variable are 0.348 and 0.476, respectively; that is, 34.8% of the drugs appear in the training set. For group 2, the mean and standard deviation of the indicator variable are 0.345 and 0.475, respectively. ...
