Derivatives of functions are computed using differential calculus. A derivative in calculus is defined as “the rate of change of quantity y with respect to quantity x”. This sounds very similar to the ...

This article will discuss the usage of derivatives in economics, but will not explain how to calculate derivatives. Derivatives are widely applied in economic modeling and theory, because they are an ...

We present a simple way to estimate the effects of changes in a vector of observable variables X on a limited dependent variable Y when Y is a general nonseparable function of X and unobservables. We ...

Since the weighted average derivatives do not rely on parametric specifications for the regression functions, the identified set is well-defined without any functional-form assumptions. Under general ...

Important applications include semiparametric linear regression with censored responses and semiparametric regression predictors. Unlike the existing penalized maximum likelihood estimators, the ...

In this paper tuning algorithm of variable fractional PID controller for switching objective function is presented. The time constant parameters of PID controller are obtained by well-known, ...
