Coefficient Of Determination - Interpretation - In A Linear Model
... a linear model of the form where, for the ith case, is the response variable, are p regressors, and is a mean zero error term ... combination of the regressors (explanatory variables) in X ... R2 is often interpreted as the proportion of response variation "explained" by the regressors in the model ...
Introduction To Linear Regression - Assumptions
... make a number of assumptions about the predictor variables, the response variables and their relationship ... This essentially means that the predictor variables x can be treated as fixed values, rather than random variables ... This means, for example, that the predictor variables are assumed to be error-free, that is they are not contaminated with measurement errors ...
Lack-of-fit Sum Of Squares - Mathematical Details
... Consider fitting a line with one predictor variable ... Define i as an index of each of the n distinct x values, j as an index of the response variable observations for a given x value, and ni as the number ... The value of each response variable observation can be represented by Let be the least squares estimates of the unobservable parameters α and β based on the observed values of x i ...
Introduction To Linear Regression - Interpretation
... to identify the relationship between a single predictor variable xj and the response variable y when all the other predictor variables in the model are “held fixed” ... results, as some of the regressors may not allow for marginal changes (such as dummy variables, or the intercept term), while others cannot be held fixed (recall the example from the ... other covariate captures all the information in xj, so that once that variable is in the model, there is no contribution of xj to the variation in y ...
Quantitative Structure–activity Relationship
... regression models, QSAR regression models relate a set of "predictor" variables (X) to the potency of the response variable(Y), while classification QSAR models relate the predictor variables to a categorical ... descriptors of chemicals the QSAR response-variable could be a biological activity of the chemicals ... property or a reactivity are modeled as response variable ...

Famous quotes containing the words variable and/or response:

    Walked forth to ease my pain
    Along the shore of silver streaming Thames,
    Whose rutty bank, the which his river hems,
    Was painted all with variable flowers,
    Edmund Spenser (1552?–1599)

    I am accustomed to think very long of going anywhere,—am slow to move. I hope to hear a response of the oracle first.
    Henry David Thoreau (1817–1862)
