Functions for the Lognormal Distribution
The lognormal distribution
(Limpert et al. (2001) <10.1641>)
can characterize uncertainty that is bounded by zero.
This package provides estimation of distribution parameters, computation of
moments and other basic statistics, and an approximation of the distribution
of the sum of several correlated lognormally distributed variables
(Lo 2013 <10.12988>).10.12988>10.1641>
Support common case of estimating standard error in the presence of correlations:
EstimateSumLognormal by default now returns NA if there are NA values in terms.
New argument na.rm = TRUE allows for previous behaviour of neglecting those terms.
- Computate of effective number of observations
- fixed bracketing bug in formula
- better dealing with NA at begin or end
