The second derivative can be interpreted as the derivative of the first derivative. For a single variable function \(f(x)\), its derivative is also a single variable function \(f'(x)\) that takes an ...

Abstract: This manuscript presents a new approach to work with concepts of interval calculus, such as interval differentiability. Moreover, we present the relationship that there exists between our ...

Recent advances in estimation techniques have underscored the growing importance of shrinkage estimation and balanced loss functions in the analysis of multivariate normal distributions. These ...

To introduce calculus of functions of several variables. Module Summary This module, which continues and extends the work of MAS1612, develops many of the ideas that are needed when constructing ...

Abstract: A new approach is presented to enhance fuzzy modeling using multidimensional fuzzy sets directly in the fuzzy model in place of decomposed fuzzy sets by projection. The antecedent fuzzy sets ...

During the Oxford Conference of the Econometric Society in 1936, Ragnar Frisch proposed a problem of characterization of distributions based on the property of linear regression of one linear function ...
