Truncated regression model — Truncated regression models arise in econometrics in cases where observations with values in the outcome variable below or above certain thresholds systematically excluded from the sample. Therefore, whole observations are missing, so that… … Wikipedia
Linear regression — Example of simple linear regression, which has one independent variable In statistics, linear regression is an approach to modeling the relationship between a scalar variable y and one or more explanatory variables denoted X. The case of one… … Wikipedia
Tobit model — The Tobit Model is an econometric, biometric model proposed by James Tobin (1958) to describethe relationship between a non negative dependent variabley i and an independent variable (or vector) x i.The model supposes that there is a latent (i.e … Wikipedia
Censored regression model — Censored regression models commonly arise in econometrics in cases where the variable ofinterest is only observable under certain conditions. A common example is labor supply. Data is frequently available on the hours worked by employees, and a… … Wikipedia
Linear least squares (mathematics) — This article is about the mathematics that underlie curve fitting using linear least squares. For statistical regression analysis using least squares, see linear regression. For linear regression on a single variable, see simple linear regression … Wikipedia
Inverse Mills ratio — In statistics, the inverse Mills ratio, named after John P. Mills, is the ratio of the probability density function to the cumulative distribution function of a distribution. Use of the inverse Mills ratio is often motivated by the following… … Wikipedia
Tobit-Modell — Das Tobit Modell ist ein auf James Tobin zurückgehendes ökonometrisches Modell zur Analyse beschränkt abhängiger Variablen (censored variables). Da die abhängige Variable nur auf einem bestimmten Wertebereich existiert, sind normale… … Deutsch Wikipedia
Errors-in-variables models — In statistics and econometrics, errors in variables models or measurement errors models are regression models that account for measurement errors in the independent variables. In contrast, standard regression models assume that those regressors… … Wikipedia
Linear least squares/Proposed — Linear least squares is an important computational problem, that arises primarily in applications when it is desired to fit a linear mathematical model to observations obtained from experiments. Mathematically, it can be stated as the problem of… … Wikipedia
