EIW Distribution for Arginine Vasopressin in Normal Women and Men

In this paper we determine a greater sensitivity of the HPA axis to low-dose PHYSO in normal men than in normal women, which likely is mediated by increased secretion of AVP. The lack of difference in side effects between the two groups of subjects and the lack of significant correlations between presence or absence of side effects and hormone responses in either group suggest that the increased hormone responses in the men were due to increased responsivity of central cholinergic systems and not to a nonspecific stress response. A length-biased of the exponentiated inverted Weibull (EIW) distribution, is named as the length-biased exponentiated inverted Weibull (LBEIW). Some probability functions are derived, including the moments of this distribution. The length-biased inverted Weibull (LBIW) distribution is presented as a special case of the LBEIW distribution and Maximum likelihood estimation method is employed to parameter estimation.
