regression
n 1: an abnormal state in which development has stopped
prematurely [synonym: {arrested development}, {fixation},
{infantile fixation}, {regression}]
2: (psychiatry) a defense mechanism in which you flee from
reality by assuming a more infantile state
3: the relation between selected values of x and observed values
of y (from which the most probable value of y can be
predicted for any value of x) [synonym: {regression}, {simple
regression}, {regression toward the mean}, {statistical
regression}]
4: returning to a former state [synonym: {regression}, {regress},
{reversion}, {retrogression}, {retroversion}]

Regression \Re*gres"sion\ (r?*gr?sh"?n), n. [L. regressio: cf.
F. r['e]gression.]
The act of passing back or returning; retrogression;
retrogradation. --Sir T. Browne.
[1913 Webster]

{Edge of regression} (of a surface) (Geom.), the line along
which a surface turns back upon itself; -- called also a
{cuspidal edge}.

{Regression point} (Geom.), a cusp.
[1913 Webster]

  • Support Vector Regression vs. Linear Regression - Cross Validated
    Linear regression can use the same kernels used in SVR, and SVR can also use the linear kernel Given only the coefficients from such models, it would be impossible to distinguish between them in the general case (with SVR, you might get sparse coefficients depending on the penalization, due to $\epsilon$-insensitive loss)
  • regression - Why do we say the outcome variable is regressed on the . . .
    The word "regressed" is used instead of "dependent" because we want to emphasise that we are using a regression technique to represent this dependency between x and y So, this sentence "y is regressed on x" is the short format of: Every predicted y shall "be dependent on" a value of x through a regression technique
  • regression - When is R squared negative? - Cross Validated
    Also, for OLS regression, R^2 is the squared correlation between the predicted and the observed values Hence, it must be non-negative For simple OLS regression with one predictor, this is equivalent to the squared correlation between the predictor and the dependent variable -- again, this must be non-negative
  • What is the lasso in regression analysis? - Cross Validated
    LASSO regression is a type of regression analysis in which both variable selection and regulization occurs simultaneously This method uses a penalty which affects they value of coefficients of regression
  • When conducting multiple regression, when should you center your . . .
    In some literature, I have read that a regression with multiple explanatory variables, if in different units, needed to be standardized (Standardizing consists in subtracting the mean and dividin
  • Linear regression when independent variable are count data
    The Ys, on the other hand, are continuous and can assume any numerical value, either positive or negative Initially, my approach was to apply linear regression to model this relationship However, given the specific nature of the Xs as count variables, I've grown uncertain about the appropriateness of using linear regression
  • How to derive the standard error of linear regression coefficient
    another way of thinking about the n-2 df is that it's because we use 2 means to estimate the slope coefficient (the mean of Y and X) df from Wikipedia: " In general, the degrees of freedom of an estimate of a parameter are equal to the number of independent scores that go into the estimate minus the number of parameters used as intermediate steps in the estimation of the parameter itself "
  • What is the difference between logistic regression and neural networks . . .
    How do we explain the difference between logistic regression and neural network to an audience that have no background in statistics?
  • Interpretation of log transformed predictors in logistic regression
    One of the predictors in my logistic model has been log transformed How do you interpret the estimated coefficient of the log transformed predictor and how do you calculate the impact of that pred
