Simple Le Cam optimal inference for the tail weight of multivariate Student $t$ distributions: testing procedures and estimation
local asymptotic normality locally asymptotically maximin tests one-step estimation Student t distribution tail weight
2013/5/21
The multivariate Student $t$ distribution is at the core of classical statistical inference and is also a well-known model for empirical financial data. In the present paper, we propose optimal (in th...

Robust and Trend Following Student's t Kalman Smoothers
2013/3/22
We present a Kalman smoothing framework based on modeling errors using the heavy tailed Student's t distribution, along with algorithms, convergence theory, open-source general implementation, and sev...
The student's dilemma: ranking and improving prediction at test time without access to training data
The student's dilemma ranking improving prediction test time without access training data
2013/3/13
The standard approach to rank the performance of several classifiers for a given classification problem is via an independent labeled validation dataset. However, in various applications only unlabele...

Program evaluation survey (PES) by students in higher education is one of the range of evaluations of academic programs. Others are course evaluation, teaching skills evaluation; and surveys of facili...
Gaussian Process Regression with a Student-t Likelihood
Gaussian process robust regression Student-t likelihood
2011/7/6
This paper considers the robust and efficient implementation of Gaussian process regression with a Student-t observation model. The challenge with the Student-t model is the analytically intractable i...
Using Deductions from Assessment Studies towards Furtherance of the Academic Program: An Empirical Appraisal of Institutional Student Course Evaluation

2011/6/28
The regular evaluation of ongoing activities under academic programs is required evidence towards academic development. Indeed, such evaluations generally involve data collection on a Likert type item...
Risk,VaR,CVaR and their associated Portfolio Optimizations when Asset Returns have a Multivariate Student T Distribution
VaR CVaR Portfolio Optimization VaR Optimization CVaR Optimization Optimisation
2011/2/28
We show how to reduce the problem of computing VaR and CVaR with Student T return distributions to evaluation of analytical functions of the moments. This allows an analysis of the risk properties of ...
