  2. Predetermined variables - Wikipedia

    en.wikipedia.org/wiki/Predetermined_variables

    If the shock affects current consumption, predeterminedness (defined now as lags only) provides potential instruments--lagged values of the variable. Predeterminedness, or sequential exogeneity, is commonly invoked in dynamic panel models. Predetermined variables can be shown as: E(u is |x it) =0 where s > t.

  3. Factor analysis - Wikipedia

    en.wikipedia.org/wiki/Factor_analysis

    Factor analysis is a statistical method used to describe variability among observed, correlated variables in terms of a potentially lower number of unobserved variables called factors. For example, it is possible that variations in six observed variables mainly reflect the variations in two unobserved (underlying) variables.

  4. Factor analysis of mixed data - Wikipedia

    en.wikipedia.org/wiki/Factor_analysis_of_mixed_data

    The data include quantitative variables =, …, and qualitative variables =, …,.. is a quantitative variable. We note: . (,) the correlation coefficient between variables and ;; (,) the squared correlation ratio between variables and .; In the PCA of , we look for the function on (a function on assigns a value to each individual, it is the case for initial variables and principal components ...

    en.wikipedia.org/wiki/Design_of_experiments

    The same is true for intervening variables (a variable in between the supposed cause (X) and the effect (Y)), and anteceding variables (a variable prior to the supposed cause (X) that is the true cause). When a third variable is involved and has not been controlled for, the relation is said to be a zero order relationship. In most practical ...

  6. One-factor-at-a-time method - Wikipedia

    en.wikipedia.org/wiki/One-factor-at-a-time_method

    The one-factor-at-a-time method, [1] also known as one-variable-at-a-time, OFAT, OF@T, OFaaT, OVAT, OV@T, OVaaT, or monothetic analysis is a method of designing experiments involving the testing of factors, or causes, one at a time instead of multiple factors simultaneously.

  7. Dependent and independent variables - Wikipedia

    en.wikipedia.org/wiki/Dependent_and_independent...

    It is possible to have multiple independent variables or multiple dependent variables. For instance, in multivariable calculus, one often encounters functions of the form z = f(x,y), where z is a dependent variable and x and y are independent variables. [8] Functions with multiple outputs are often referred to as vector-valued functions.

  8. Latent variable model - Wikipedia

    en.wikipedia.org/wiki/Latent_variable_model

    The Rasch model represents the simplest form of item response theory. Mixture models are central to latent profile analysis.. In factor analysis and latent trait analysis [note 1] the latent variables are treated as continuous normally distributed variables, and in latent profile analysis and latent class analysis as from a multinomial distribution. [7]

  9. Predictor–corrector method - Wikipedia

    en.wikipedia.org/wiki/Predictor–corrector_method

    A simple predictor–corrector method (known as Heun's method) can be constructed from the Euler method (an explicit method) and the trapezoidal rule (an implicit method). Consider the differential equation ′ = (,), =, and denote the step size by .
