Abstract
A distribution of a sum of identically distributed Gamma-
variables correlated according to an "exponential" autocorrelation law pkj =
p'k-jl(k, j = 1, . . . n) where pkj is the correlation coefficient between the
kth and jth random variables and 0 < p < 1 is a given number is derived. An
äpproximate" distribution of the sum of these variables under the assumption
that the sum itself is a Gamma-variable is given. A comparison between exact
and approximate distributions for certain values of the 'correlation coefficient, the
number of variables in the sum and the values of parameters of the initial dis-
tributions is presented.
