pltprior {RCASPAR}R Documentation

A function to visualize the shape of the prior on the weights with the chosen q and s parameters.

Description

This function helps visualize the effect of the parameters q and s on the prior distribution used on the weights.

Usage

pltprior(q, s)

Arguments

q

One of the two parameters used to determine the prior on the weights.

s

The second of two parameters used to determine the prior on the weights.

Details

The prior assumed on the weights in the objective function takes on the following formulation:

[L_q(β; q, s)= \frac{\frac{{q^{(q-1)}} {q}} {2sΓ(\frac{{1}{q}})}} exp(\frac{{-1}{qs^q}} |\emph{weights}|^q)

Value

A 3D plot of the value of the prior taking into consideration only two weights
