Goat mastitis detection using daily records of milk conductivity: comparative results of different algorithms
Milk electrical conductivity is employed for mastitis detection in cows due to its automation, low cost, and infection detectability at early stage. Nevertheless, the number of publications about its use in dairy goats is scarce. The aim of this study was to check and compare the detectability of goat mastitis (sensitivity and specificity) using different algorithms, constructed with individual...
متن کاملReflecting Uncertainty about Economic Theory when Estimating Consumer Demand
Economic theory provides a great deal of information about demand models. Specifically, theory can dictate many relationships that expenditure and price elasticities should fulfill. Unfortunately, analysts cannot be certain whether these relationships will hold exactly. Many analysts perform hypothesis tests to determine if the theory is correct. If the theory is accepted then the relationships...
متن کاملEstimating milk yield of sows.
Hourly milk yields were obtained for nine consecutive hours at d 14 of lactation from 92 crossbred (four breed) sows during their first and second lactations. Additionally, milk yields were obtained at d 14 and 20 of lactation from 175 mature Yorkshire X Landrace sows for nine consecutive hours. Each measurement (4,806 observations) was obtained by weighing the pigs before and after each hourly...
متن کاملEstimating Aversion to Uncertainty
It is intuitive that decision-makers might have attitudes towards uncertainty just as they might have attitudes towards risk. However, it is only recently that this intuitive notion has been formalized and axiomatically characterized. We estimate the extent of uncertainty aversion in a manner that is parsimonious and consistent with theory. We demonstrate that one can jointly estimate attitudes...
متن کاملEstimating Measurement Uncertainty
Most analytical methods are relative and hence require calibration. Calibration measurements are normally performed with reference materials or calibration standards. Typically least squares methods have been employed in such a manner as to ignore uncertainties associated with the calibration standards. However different authors [3, 4, 11] have shown that by taking into account the uncertaintie...
