A derivative of a function of two or more variables with respect to one variable, the other(s) being treated as constant.
‘In this section, we explain the Hadamard transform and prove a number of technical lemmas expressing the partial derivatives of the likelihood function.’
‘Cursory examination of run times also supports the importance of computing partial derivatives analytically rather than numerically.’
‘The overall marginal impact on total costs of production of an incremental unit of output i is found by taking the partial derivative of the estimated cost function with respect to output i, at the sample means of the variables.’
‘But the concept of variation in this case is just that of a derivative, or more precisely, that of a partial derivative, with respect to each population's probability of extinction.’
‘From this partial derivative we can get another picture of similarity in culture and workplace conditions between different regions of the world and the U.S. market.’
