چکیده
The experiment was done in a lemon grove on the high school farm in Fillmore, Ventura County, California. The grove is managed using IPM methods and is under successful biological control for California red scale. Lorzban is sprayed annually on the ground for ant control but the area we sampled was not sprayed during our experiment. No other pesticides or oil treatments are used. Aphytis melinus are sometimes released in the area but no releases occurred in this grove during the four years of our experiments.

Classical and Bayesian Inference in Two Parameter Exponential Distribution with Randomly Censored Data
Abstract. This paper deals with the classical and Bayesian estimation for two parameter exponential distribution having scale and location parameters with randomly censored data. The censoring time is also assumed to follow a two parameter exponential distribution with different scale but same location parameter. The main stress is on the location parameter in this paper. This parameter has not...
متن کاملParameter Estimation of Some Archimedean Copulas Based on Minimum Cramér-von-Mises Distance
The purpose of this paper is to introduce a new estimation method for estimating the Archimedean copula dependence parameter in the non-parametric setting. The estimation of the dependence parameter has been selected as the value that minimizes the Cramér-von-Mises distance which measures the distance between Empirical Bernstein Kendall distribution function and true Kendall distribution functi...
متن کاملEvaluation of estimation methods for parameters of the probability functions in tree diameter distribution modeling
One of the most commonly used statistical models for characterizing the variations of tree diameter at breast height is Weibull distribution. The usual approach for estimating parameters of a statistical model is the maximum likelihood estimation (likelihood method). Usually, this works based on iterative algorithms such as Newton-Raphson. However, the efficiency of the likelihood method is not...
متن کاملEstimation of parameter of proportion in Binomial Distribution Using Adjusted Prior Distribution
Historically, various methods were suggested for the estimation of Bernoulli and Binomial distributions parameter. One of the suggested methods is the Bayesian method, which is based on employing prior distribution. Their sound selection on parameter space play a crucial role in reducing posterior Bayesian estimator error. At times, large scale of the parametric changes on parameter space bring...
متن کاملMethods for Parameter Estimation of the Lorenz Functional Forms and Compare Them Based on Household Expenses Data
In the modern society and specially in our country discussion of poverty, wealth and social justice are the most important arguments of public and private circles. The most important graphical tools which are used to describe the quantity of centralization like wealth in a society is Lorenz curve. In these situations, most of econometricians measure the economic inequalities. In the discrete ca...
متن کاملThree-parameter Kappa distribution and its fitting to the whole monthly rainfall data of Abali station in Tehran province
Kappa distribution is a positively skewed distribution which is used in analyzing precipitation, wind speed and streamflow data. In this paper, first a three-parameter Kappa distribution that introduced by Park et al. (2009) is studied and then four different methods of estimation including Moments, L-Moments, Maximum Likelihood and Maximum Product Spacing Method are presented in order to estim...
