Physiological responses to drought stress in wild relatives of wheat: implications for wheat improvement
Alireza Pour-Aboughadareh,Jafar Ahmadi,Ali Ashraf Mehrabi,Alireza Etminan,Mohammad Moghaddam,Kadambot H. M. Siddique +5 more
TL;DR: Wild progenitors of common wheat are a potential source of tolerance to biotic and abiotic stresses and four species of wild relatives responded well to drought stress with a lower percentage decline for most traits and high values for the first two components.
Journal ArticleDOI
Log-Gamma generated families of distributions
TL;DR: In this paper, two new general families of continuous distributions, generated by a distribution F and two positive real parameters α and β which control the skewness and tail weight of the distribution, are presented.
Journal ArticleDOI
Estimation and prediction in a two-parameter exponential distribution based on k-record values under LINEX loss function
TL;DR: In this paper, a Bayesian estimation for the two parameters of the exponential distribution are obtained based on k-record values under Linear-Exponential LINEX loss function, and the admissibility of some estimators are discussed.
Journal ArticleDOI
Bayesian estimation and prediction for some life distributions based on record values
Jafar Ahmadi,Mahdi Doostparast +1 more
TL;DR: In this article, a Bayesian estimation for the two parameters of some life distributions, including Exponential, Weibull, Pareto and Burr type XII, are obtained based on upper record values.
Journal ArticleDOI
Bayes estimation based on k-record data from a general class of distributions under balanced type loss functions
TL;DR: In this article, a semi-parametric class of distributions including exponential, Weibull, Pareto, Burr type XII and so on is considered, and the results are presented under the balanced versions of two well-known loss functions, namely squared error loss (SEL) and Varian's linear-exponential (LINEX) loss.
