Economic analysis of the risk of replacing corn grains (Zea mays) with pearl millet grains (Pennisetum glaucum) in the diet of feedlot cattle [PDF]

open access: yesCiência Rural, 2020
: The goal of the present study was to assess the economic viability relating to the risk of replacing corn with pearl millet in diets with 80% concentration for feedlot cattle confined for 89 days. Replacement levels were: 0, 33, 66, and 100%.

Risk analysis of the economic viability of feedlot aberdeen angus steers fed with different proportions of concentrate

open access: yesBioscience Journal, 2017
The economic viability of feedlot Aberdeen Angus steers fed with diets composed of different concentrate levels (CL) in dry matter (25, 40, 55 or 70%) was estimated using Monte Carlo simulation combined with Spearman rank correlation, considering nine ...

A Stochastic Approximation Method [PDF]

open access: yesThe Annals of Mathematical Statistics, 1951
Let M(x) denote the expected value at level x of the response to a certain experiment. M(x) is assumed to be a monotone function of x but is unknown to the experimenter, and it is desired to find the solution x = θ of the equation M(x) = α, where a is a given constant.

Stochastic Generalized Method of Moments [PDF]

open access: yesJournal of Computational and Graphical Statistics, 2011
The generalized method of moments (GMM) is a very popular estimation and inference procedure based on moment conditions. When likelihood-based methods are difficult to implement, one can often derive various moment conditions and construct the GMM objective function.
