For decades, performance comparisons between real estate and financial assets have repeatedly indicated that private real estate investment exhibits significantly higher risk-adjusted returns than publicly traded financial assets such as common stocks. That is, there is an apparent “real estate risk premium puzzle.” In this paper, we find that the seemingly superior risk-adjusted returns of rea...

A growing number of studies have focused on evaluating spectral indices in terms of their sensitivity to vegetation biophysical parameters, as well as to external factors affecting canopy reflectance. In this context, leaf and canopy radiative transfer models are valuable for modeling and understanding the behavior of such indices. In the present work, PROSPECT and SAILH models have been used t...

UNLABELLED Admission to one of the state hospitals in West Virginia is gained through a legal proceeding which is initiated on a county level. It was hypothesized that involuntary psychiatric admission patterns from the Sharpe Hospital catchment area do not have a direct correlation with county population. METHODS Sharpe Hospital admissions data for a one year period were collected and demogr...

This paper investigates and compares the performances of the optimal portfolio selected by using the Orthogonal GARCH (OGARCH) Model, Markov Switching Model and the Exponentially Weighted Moving Average (EWMA) Model in a fund of hedge funds. These models are used to calibrate the returns of four HFRX indices from which the optimal portfolio is constructed using the Mean-Variance method. The per...

Abstract Background Recently, South Dakota Department of Game, Fish, and Parks (SDGFP), has undertaken a suite rigorous acoustic telemetry studies. The goals scope the individual research projects vary but all use same receiver array throughout Lake Sharpe in central Dakota. Prior to initiating studies, we sought describe detection probability receivers from representation habitats within Sharp...

Portfolios of assets whose returns have the Gaussian mixture distribution are optimized in the static setting to find portfolio weights and efficient frontiers using the probability of outperforming a target return and Hodges’ modified Sharpe ratio objective functions. The sensitivities of optimal portfolio weights to the probability of the market being in the distressed regime are shown to giv...

A simple equilibrium restriction identifies time-varying components of expected returns. Using data from the Fama and French threeand fivefactor models and momentum, we use this restriction to predict factor returns out of sample. We derive a policy for timing exposures to these components and find the modified portfolio generates returns with higher out-of-sample Sharpe ratios than the underly...

The building blocks of the Sharpe ratio—expected returns and volatilities— are unknown quantities that must be estimated statistically and are, therefore, subject to estimation error. This raises the natural question: How accurately are Sharpe ratios measured? To address this question, I derive explicit expressions for the statistical distribution of the Sharpe ratio using standard asymptotic t...

Background and Objective Evaluation of dental attrition is an easy and relatively accurate approach to estimating the age of an adult either ante- or postmortem for some specific population. Dental attrition represents a progressive physiological age change that can be measured using variety of indices to aid as an adjunct in forensic age estimation. Some of the previously proposed indices have...

Abstract This study compares the performance of five portfolios built according to level integration environmental, social and governance values in case South Africa, over period four years from 2 January 2019 29 December 2022. The were (1) two dimensions ESG ratings (responsible irresponsible) (2) levels implication (partially significantly), there is also a portfolio for non-engaged companies...
