Query: Large--Scale Angular Correlations in CDM Models   We generate artificial Lick maps using $N$--body simulations and compare the
angular correlation function, $w(\vartheta)$, measured from the simulations
with the APM correlation. For the Gaussian CDM model, neither the standard
biassed model nor a more evolved model (as suggested by the COBE data),
reproduce the correlations on large angular scales. We come to a similar
conclusion about CDM models with positively skewed initial fluctuation
distributions. In contrast, models with initially negatively skewed
fluctuations produce a $w(\vartheta)$ that declines much more gently on large
scales. Such models are therefore in principle capable of reconciling the lack
of large--scale power of the CDM spectrum with the observed clustering of APM
galaxies.
