Stretching the Horizon of a Higher Dimensional Small Black Hole [PDF]
, 2005 There is a general scaling argument that shows that the entropy of a small black hole, representing a half-BPS excitation of an elementary heterotic string in any dimension, agrees with the statistical entropy up to an overall numerical factor.

Analysis Approach: Item Statistics and Factor Analysis
, 2020 Using dataset from Dataset of Vietnamese students' learning habits during COVID-19 by Trung et al. (2020), this paper answer two research questions. First, should any items be dropped to improve alpha co-efficient? Second, do the items measure one of the three concepts (Necessity for self-learning during COVID-19, Effectiveness for self-learning ...

Statistical analysis of sparse approximate factor models [PDF]
Electronic Journal of Statistics, 2020 The authors consider a sequence of \(n\) i.i.d.~observations of a \(p\)-dimensional random vector \((X_i)\), having the factor structure \(X_i=\Lambda\,F_i+\epsilon_i\), where \(\Lambda\) is the loading \(p\times m\) matrix, \(F_i\) is the vector of centred factor variables and \(\epsilon_i\) are the errors -- the idiosyncratic variables. The dimension

Understanding and Improving the Wang-Landau Algorithm [PDF]
, 2005 We present a mathematical analysis of the Wang-Landau algorithm, prove its convergence, identify sources of errors and strategies for optimization. In particular, we found the histogram increases uniformly with small fluctuation after a stage of initial ...
