Estimation of Water Demand of Agriculture Sector by Water-Yield Function (Case Study: Sistan Province)
In this study, yield-water and profit function was used to obtain water demand function in agriculture sector. The results showed that the ratio of actual to potential Evapotranspiration had positive, significant effecton the ratio of actual to potential yield for wheat and barley. Also, square ratio of actual to potential Evapotranspiration had negative, significant relationship. After estimat...
متن کاملEstimation of 'quality per call' in modelled telephone conversations
We present a method to estimate the perceived listening quality by a subscriber at the end of a common voice telephony conversation. This method was recently introduced in ETSI STQ mobile and was approved as TR 102 506 ‘Speech Quality per Call’ [1]. The idea is to calculate this “speech-quality-per-call” value based on short-term listening quality scores (so-called Mean Opinion Scores, MOS), as...
متن کاملOn doubly robust estimation in a semiparametric odds ratio model.
We consider the doubly robust estimation of the parameters in a semiparametric conditional odds ratio model. Our estimators are consistent and asymptotically normal in a union model that assumes either of two variation independent baseline functions is correctly modelled but not necessarily both. Furthermore, when either outcome has finite support, our estimators are semiparametric efficient in...
متن کاملInverse odds ratio-weighted estimation for causal mediation analysis.
An important scientific goal of studies in the health and social sciences is increasingly to determine to what extent the total effect of a point exposure is mediated by an intermediate variable on the causal pathway between the exposure and the outcome. A causal framework has recently been proposed for mediation analysis, which gives rise to new definitions, formal identification results and n...
متن کاملOdds Ratio, Hazard Ratio and Relative Risk
Odds ratio (OR) is a statistic commonly encountered in professional or scientific medical literature. Most readers perceive it as relative risk (RR), although most of them do not know why that would be true. But since such perception is mostly correct, there is nothing (or almost nothing) wrong with that. It is nevertheless useful to be reminded now and then what is the relation between the rel...
