Functions for the Lognormal Distribution

The lognormal distribution (Limpert et al. (2001) ) 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 ).


lognorm 0.1.4

Support common case of estimating standard error in the presence of correlations: function seCor.

lognorm 0.1.3

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.

lognorm 0.1.2

  • Computate of effective number of observations
    • fixed bracketing bug in formula
    • better dealing with NA at begin or end

lognorm 0.1.1

basic setup
