Description

simulates abundance data and calculates overlap for changing variances

Usage

2
changingvar.beta(repeatings = 100, days = c(730, 680, 550, 365, 180, 90, 7),
  n = 1000)

Arguments

repeatings

numeric (whole numbers); Determines how often the whole procedure (data producing and calculation of the overlap) shall be repeated.

days

vector of numerics (whole numbers); determines the length of the time range over which the data shall stretch.

n

numeric (whole number); Determines the sample size for creating the datasets. Will be passed as as 'n' argument to to the NormData() function.

Details

Will determine the overlap-measures given by OLest for two simulated datasets both coming from a beta distribution with the sample size given by n. This will be done for every number of days given by days which determines the time-range over which the dataset spreads. And for every number of day there will be as many overlaps will be determined as the repeatings argument says.

Value

a list. First index level determines the way of estimating the pdf so it has the three indexes: 'kernel', 'fitdistr' and 'normalize'. The second index-level is the chosen numbers of days and the last the number of the repeating. In there are the results as returned by OLE function. To illustrate: list[[kernel]][[numbers of days]][[repeating]].
