GetEstimate_ROUGH {HydroPortailStats} | R Documentation |
Rough estimate of a distribution
Description
Returns a rough first-guess estimate of a distribution. This estimate may be poor but it solely aims at being used as a starting point for more advanced estimation approaches (e.g. max-likelihood or Bayesian). It is therefore chosen as an easy-to-compute explicit formula, robust and error-proof.
Usage
GetEstimate_ROUGH(y, dist)
Arguments
y |
numeric vector, data |
dist |
character, distribution name |
Value
A list with the following components:
par |
numeric vector, estimated parameter vector. |
obj |
numeric, objective fonction (NA for this estimate) |
ok |
logical, did computation succeed? |
err |
integer, error code (0 if ok) |
message |
error message |
Examples
y=c(9.2,9.5,11.4,9.5,9.4,9.6,10.5,11.1,10.5,10.4)
GetEstimate_ROUGH(y,'Normal')
GetEstimate_ROUGH(y,'LogNormal')
