* '''Approximations - ''' Minimac4 uses some simple approximations to speed up the imputation analyses. The levels of approximation can be controlled by the parameters <code>--probThreshold</code>, <code>--diffThreshold</code>, and <code>--topThreshold</code> (details given in Minimac4 Usage). Higher levels of approximation will reduce the compute time but also marginally reduce the imputation accuracy. We recommend using the default values.
