Web: The endogenous variable (s). : The exogenous variable (s) : The instrument (s) (often denoted ) The explicit formula for the LIML is: [14] where M = I − X (X ′X)−1X ′, and λ is the smallest characteristic root of the matrix: where, in a similar way, Mi = I − Xi (Xi′Xi)−1Xi′ . WebEndogenous variables are used in econometrics and sometimes in linear regression. They are similar to (but not exactly the same as) dependent variables. Endogenous variables have values that are determined by other variables in the system (these “other” variables are called exogenous variables). rcgp research paper of the year 2022
