Nonparametric regression can be considered as a problem of model choice. In this paperwe present the results of a simulation study in which several nonparametric regressiontechniques including wavelets and kerne
One major assumption of Logistic Regression is that each observation provides equal information. Analytic Solver DataScienceoffers an opportunity to provide a Weight Variable. Using aWeight Variableallows the user to allocate a weight to each record. A record with a large weight will influence the m...
Problem Description Logistic regression is a special type of regression in which the goal is to model the probability of something as a function of other variables. Consider a set of predictor vectors x1,…,xN where N is the number of observations and xi is a column vector containing the val...
When a DS predictor is paired with a DS response, problems of spurious regression appear [2]. This is true even if the series are generated independently from one another, without any confounding. The problem is complicated by the fact that not all DS series are trending. Consider the ...
Berkson (1980) conjectured that minimum x2 was a superior procedure to that of maximum likelihood, especially with regard to mean squared error. To explore his conjecture, we analyze his (1955) bioassay problem related to logistic regression. We consider not only the criterion of mean squared ...

Stepwise regression is the step-by-step iterative construction of aregressionmodel that involves the selection of independent variables to be used in a final model. It involves adding or removing potential explanatory variables in succession and testing for statistical significance after each iteration. ...
Linear regression, also known as simple linear regression or bivariate linear regression, is used when we want to predict the value of a dependent variable based on the value of an independent variable. For example, you could use linear regression to understand whether exam performance can be ...
This limits the test, however, to values of L greater than p + q, since the degrees of freedom must be positive. Similar adjustments can be made for general regression models, but lbqtest does not do so by default. Another test for "overall" lack of autocorrelation is a runs test, ...
