چکیده
A regular variable holds, at any one time, a single value, be it numeric or otherwise. In contrast, a random variable (RV) holds a distribution over values, be they numeric or otherwise. For example, the outcome of a future toss of a fair coin can be captured by a random variable X holding the following distribution: ’HEAD’ with probability 0.5, and ’TAIL’ with probability 0.5 . We will use uppercase characters to denote random variables, and their lowercase equivalents to denote the values taken by those random variables. The following are commonly used notations to represent probabilities:

Support vector regression with random output variable and probabilistic constraints
Support Vector Regression (SVR) solves regression problems based on the concept of Support Vector Machine (SVM). In this paper, a new model of SVR with probabilistic constraints is proposed that any of output data and bias are considered the random variables with uniform probability functions. Using the new proposed method, the optimal hyperplane regression can be obtained by solving a quadrati...

متن کاملNon-parametric entropy estimators based on simple linear regression
Estimators for differential entropy are proposed. The estimators are based on the second order expansion of the probability mass around the inspection point with respect to the distance from the point. Simple linear regression is utilized to estimate the values of density function and its second derivative at a point. After estimating the values of the probability density function at each of th...
متن کاملA simple method of sample size calculation for linear and logistic regression.
A sample size calculation for logistic regression involves complicated formulae. This paper suggests use of sample size formulae for comparing means or for comparing proportions in order to calculate the required sample size for a simple logistic regression model. One can then adjust the required sample size for a multiple logistic regression model by a variance inflation factor. This method re...
متن کاملOn Diagnostics in Stochastic Restricted Linear Regression Models
The aim of this paper is to propose some diagnostic methods in stochastic restricted linear regression models. A review of stochastic restricted linear regression models is given. For the model, this paper studies the method and application of the diagnostic mostly. Firstly, review the estimators of this model. Secondly, show that the case deletion model is equivalent to the mean shift outlier ...
