Statistical Inference in Autoregressive Models with Non-negative Residuals
Normal residual is one of the usual assumptions of autoregressive models but in practice sometimes we are faced with non-negative residuals case. In this paper we consider some autoregressive models with non-negative residuals as competing models and we have derived the maximum likelihood estimators of parameters based on the modified approach and EM algorithm for the competing models. Also,...
متن کاملStatistical analyses
To account for the non-independence of individual observations within a year, and the large differences in sample size among groups, analyses were, where possible, performed on yearly means for the relevant sub-group. When appropriate, yearly means were squareroot or arc-sine transformed before analysis. All presented means and parameter estimates are back-transformed. All statistical analyses ...
متن کاملA new statistical method for design and analyses of component tolerance
Tolerancing conducted by design engineers to meet customers’ needs is a prerequisite for producing high-quality products. Engineers use handbooks to conduct tolerancing. While use of statistical methods for tolerancing is not something new, engineers often use known distributions, including the normal distribution. Yet, if the statistical distribution of the given variable is unknown, a new sta...
متن کاملStatistical Graphics of Pearson Residuals in Survey Logistic Regression Diagnosis
Survey data logistic regression analysis, as computationally available in SAS SURVEYLOGISTIC procedure, has been widely conducted in survey research practice. A set of diagnostic statistics in the procedure, borrowed from the logistic regression in generalized linear models, is used for model assessment. However, for survey data, the statistical underpinnings of these statistics may need to be ...
متن کاملHybrid Dynamical Systems : Fault Graphs , Statistical Residuals and Viterbi Algorithms
We address the problem of model-based fault diagnosis for hybrid numeric/symbolic dynamical systems. The objective is the systematic design of fault diagnosis algorithms, based on fault graphs provided by reliability analysis and on-board sensor data processing. We propose a new approach, based on hmm ideas and Viterbi algorithm. Experimental results of the proposed approach for a simulated mec...
