answer:
log-logistic
distribution :
- The log-strategic appropriation is the likelihood conveyance of
an irregular variable whose logarithm has a calculated
dispersion.
 
- It is comparative fit as a fiddle to the log-ordinary
dispersion yet has heavier tails.
 
- Not at all like the log-ordinary, its aggregate circulation
capacity can be written in shut structure.
 
it's
assumptions:
- There are a few diverse parameterizations of the circulation
being used.
 
- The one appeared here gives sensibly interpretable parameters
and a straightforward structure for the combined conveyance
function.
 
- The parameter { alpha >0}\alpha >0 is a scale parameter
and is additionally the middle of the appropriation.
 
- The parameter {beta >0}\beta >0 is a shape
parameter.
 
- The dissemination is unimodal when {beta >1}\beta>1 and
its scattering diminishes as {beta }\beta increments.
 
properties:
we have the two properties they are .,
1.Moments
2. Quantiles
