2. THE LEADING DISTRIBUTION-PARAMETERS OF ANY COMPLEX 



CHANCE-VARIABLE 



By the "leading distribution-parameters" of any complex chance- 

 variable will here be meant a certain set of distribution-parameters 

 (specified below) which would be sufficient for completely fixing the 

 distribution if it were "normal." Even when the distribution is not 

 "normal" these parameters are usually present among the other 

 parameters in the distribution-function; indeed they are often the 

 most important of the distribution-parameters. 



In order to define and formulate the "leading distribution-param- 

 eters" of any complex chance-variable Z = X -\- iY m an explicit
