Self, Peer and Teacher Assessment as Active Learning Methods
This paper provides an example of self and peer assessment among Spanish students pursuing a business administration degree (first and third year) as well as the results of our study and concluding remarks. We point out differences between the results for the firstand third-year students. Whereas students in their first year are beginners with respect to this kind of task, third-year students are proficient at this kind of assessment.
This paper examines the application of the Least Absolute Deviations (LAD) method for ridge-type parameter estimation of Seemingly Unrelated Regression Equations (SURE) models. The methodology is aimed to deal with the SURE models with non-Gaussian error terms and highly collinear predictors in each equation. Some biasing parameters used in the literature are taken and the efficiency of both Least Squares (LS) ridge estimation and the LAD ridge estimation of the SURE models, through the Mean Squared Error (MSE) of parameter estimators, is evaluated.
