“…Several bayesian shrinkage procedures have been proposed in the last years in many statistical fields. Some of them are found in Lian (2011), Beenamol et al (2012), Karagiannis et al (2015), Griffin & Brown (2017) and Torkamani & Sadeghzadeh (2017). Further, priors models in the wavelet domain were proposed since 1990s, as for example a mixture of gaussian distributions by Chipman et al (1997), mixtures of a point mass function at zero and a symmetric distribution were considered by Abramovich et al (1998), Vidakovic (1998) with the use of the t-distribution as the symmetric density in the mixture, Vidakovic & Ruggeri (2001) with the double exponential distribution, Angelini & Vidakovic (2004) with a Γ-Minimax shrinkage rule based on the Bickel distribution, Weibull prior were proposed by Reményi & Vidakovic (2015), Dirichlet-Laplace priors by Bhattacharya et al (2015), the logistic prior by Sousa et al (2021) and the symmetric beta distribution by Sousa et al (2021), among others.…”
