Regression analysis is a statistical method for analyzing a relationship between two or more variables in such a manner that one of the variables can be predicted or explained by the information on the other variables. The term “regression” was first introduced by Sir Francis Galton in the late 1800s to explain the relation between heights ...
Regression analysis is the oldest, and probably, most widely used multivariate technique in the social sciences. Unlike the preceding methods, regression is an example of dependence analysis in which the variables are not treated symmetrically. In regression analysis, the object is to obtain a prediction of one variable, given the values of the ...
Logistic regression analysis is used to examine the association of (categorical or continuous) independent variable (s) with one dichotomous dependent variable. This is in contrast to linear regression analysis in which the dependent variable is a continuous variable. The discussion of logistic regression in this chapter is brief.
Dec 10, 2013 · Regression models with one dependent variable and more than one independent variables are called multilinear regression. In this study, data for multilinear regression analysis is occur from Sakarya University Education Faculty student's lesson (measurement and evaluation, educational psychology, program development, counseling and instructional techniques) scores and their 2012- KPSS score.
Jan 1, 2017 · This paper revisits the problem of choosing ratio variables in regression analysis in Musumeci and Peterson (2011). In the application we examined, linear regressions with the ratio variable, its reciprocal or logarithm have been rejected. To avoid model misspecifications, we suggest to use nonlinear regressions on ratio variables.
Multivariate logistic regression analysis is a statistical tool that can be used to select and combine input variables which are linked to a certain outcome, for example, patient or tumour characteristics that are linked to the presence of malignancy in a pelvic mass. From: Best Practice & Research Clinical Obstetrics & Gynaecology, 2004.
Dec 1, 2014 · Meta-regression analysis, or meta-regression, is an extension to standard meta-analysis that investigates the extent to which statistical heterogeneity between results of multiple studies can be related to one or more study characteristics (Thompson & Higgins, 2002). It is very unlikely that all heterogeneity will be explained, so there will be “residual heterogeneity”, therefore random effects rather than fixed effects meta-regression is appropriate.
May 1, 2022 · The survival probability of a population at any given time is often of interest. Kaplan and Meier proposed a nonparametric method to estimate the survival probability that is the most commonly used method. 2 Define T as the response variable, time to event of interest, or survival time. The survival function is defined as S t = P an individual ...

Apr 1, 2021 · Regression analysis constitutes an important tool for investigating the effect of explanatory variables on response variables. When outliers and bias errors are present, the weighted least squares estimator can perform poorly. For this reason, alternative robust techniques have been studied in several areas of science.
