In this paper we apply the concept of generalized Lagrange multipliers, introduced by Everett [4], to the development of an algorithm for a one- period multi-product production model, where the ...

The Lagrange Multiplier (LM) test is one of the principal tools to detect ARCH and GARCH effects in financial data analysis. However, when the underlying data are non-normal, which is often the case ...

When you select the NOINT or NOSCALE option, restrictions are placed on the intercept or scale parameters. Lagrange multiplier, or score, statistics are computed in these cases. These statistics ...

In general, the iteration history consists of one line of printed output for each iteration, with the exception of the Nelder-Mead simplex method. The NLPNMS subroutine prints a line only after ...

The Nature Index 2024 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...
