BLOMEst {EWGoF} | R Documentation |
Computes the Blom's estimators of the shape and scale parameters of the Weibull distribution from an i.i.d sample x.
It also gives the sample \check{y}
after using the logarithmic transformation (\check{y}=(\check{shape})\ln(x/\check{scale})
, where \check{shape}
and \check{scale}
are the estimated shape and scale parameters).
BLOMEst(x)
x |
a numeric vector of data values. |
A list containing the following elements:
eta |
the Blom's estimator of the scale parameter of the Weibull distribution ( |
beta |
the Blom's estimator of the shape parameter of the Weibull distribution ( |
y |
the pseudo-observations |
