Bayesian and non-Bayesian regression analysis applied on wind speed data

چکیده
Statistical methods are widely used to analyze the relationship between several independent variables (predictors) and a dependent variable. As wind energy rapidly becomes an important source of renewable energy, it is prudent deeply evaluate any potential existing relationships among data. This paper aims apply frequentist statistical approach, namely, non-Bayesian Bayesian multiple linear regression speed data investigate differences two methodologies. study uses NREL from fifteen different farms. In proposed study, correlation matrix was implemented select significantly correlated all use as method followed by Random Forest machine learning technique for feature selection considering most features that will be models. We first run (non-Bayesian model) in which we variance inflation factor detect multicollinearity problem get fitted model. then approach model variables. The results both approaches show close coefficients parameters estimations. Moreover, using sample sizes hourly, daily, weekly data, found daily provide strong coefficient estimator highest R-squared compared hourly

The Analysis of Bayesian Probit Regression of Binary and Polychotomous Response Data
The goal of this study is to introduce a statistical method regarding the analysis of specific latent data for regression analysis of the discrete data and to build a relation between a probit regression model (related to the discrete response) and normal linear regression model (related to the latent data of continuous response). This method provides precise inferences on binary and multinomia...
متن کاملBayesian and Iterative Maximum Likelihood Estimation of the Coefficients in Logistic Regression Analysis with Linked Data
This paper considers logistic regression analysis with linked data. It is shown that, in logistic regression analysis with linked data, a finite mixture of Bernoulli distributions can be used for modeling the response variables. We proposed an iterative maximum likelihood estimator for the regression coefficients that takes the matching probabilities into account. Next, the Bayesian counterpart...
متن کاملBayesian Analysis of Censored Spatial Data Based on a Non-Gaussian Model
Abstract: In this paper, we suggest using a skew Gaussian-log Gaussian model for the analysis of spatial censored data from a Bayesian point of view. This approach furnishes an extension of the skew log Gaussian model to accommodate to both skewness and heavy tails and also censored data. All of the characteristics mentioned are three pervasive features of spatial data. We utilize data augme...
متن کاملNon-Bayesian Estimation and Prediction under Weibull Interval Censored Data
In this paper, a one-sample point predictor of the random variable X is studied. X is the occurrence of an event in any successive visits $L_i$ and $R_i$ :i=1,2…,n (interval censoring). Our proposed method is based on finding the expected value of the conditional distribution of X given $L_i$ and $R_i$ (i=1,2…,n). To make the desired prediction, our approach is on the basis of approximating the...
