spd.meteESF
calculates the distribution nu(e | N0, S0, E0),
the distribution of average metabolic rates across for each species in a commmunity
spd(x)
## S3 method for class 'meteESF'
spd(x)

See examples.
An object of class meteDist
. The object contains a list with the following elements.
The data used to construct the prediction
density funciton
cumulative density function
quantile funtion
random number generator
Vector of Lagrange multipliers
State variables used to constrain entropy maximization
Specifies the type of distribution is 'sad'
