identification of the best vegetation indices (vis) for use in quantitative analyzes of vegetation is one of the important issues for ecologists. the objective of this study was sensitivity evaluation of vegetation indices to a stand volume for identification of the best vegetation index (vi) in stand volume estimation using a statistical sensitivity method. also, another objective of this stud...
This study aimed at comparing the performances of distinct hedge fund strategies and assessing diversification opportunities using funds. paper analyses overall performance (as indices) for period 2001-2020. Hedge are compared alternative risk adjusted metrics; first, alpha based on four asset-pricing models (CAPM, Fama-French 3 factor, Carhart 5 factor models); then, Sharpe ratio. The findings...
In this paper, we used several elaborate return-to-risk methods to investigate the risk-adjusted performances of five soft commodities. Regarding only level risk, found that cocoa had highest risk losses, followed by orange juice. Cotton and coffee lowest losses. However, according output, cotton was worst asset in which invest because it negative average returns. contradistinction, sugar a rel...

We present a general comparison of punctual kriging based image restoration for different neighbourhood sizes. The formulation of the technique under consideration is based on punctual kriging and fuzzy concepts for image restoration in spatial domain. Three different neighbourhood windows are considered to estimate the semivariance at different lags for studying its effect in reduction of nega...
The Sharpe ratio is the prominent risk-adjusted performance measure used by practitioners. Statistical testing of this ratio using its asymptotic distribution has lagged behind its use. In this paper, highly accurate likelihood analysis is applied for inference on the Sharpe ratio. Both the oneand two-sample problems are considered. The methodology has O n−3/2 distributional accuracy and can be...
