1.7 (6 April 2009)
---
now calculating the covariance of the mean vector in C
for the predictive covariance calculation in R
implemented Student-t via scale mixtures (Geweke, 1993),

clutter in tau2i and omega2 printing
now calculating the likelihood for each sample saved
from the posterior in blasso
propogated llik to Ellik calculation in bmonomvn
capm = TRUE now default for bmonomvn, and now allowing

accumumating S != 0 and Si != 0 probabilities in
bmonomvn
added pnz argument to randmvn to allow the specification

with the market (S&P500) return to be used as a factor
fixed bug in new integrated RJMCMC implementation
forcing the first p columns to be the most observed
when using factor regressions in monomvn; may make

solutions to ignore factors by specifying an integer
argument to bmonomvn rather than TRUE
1.5 (13 Nov 2008)
---
implemented Throughton & Godsill RJ proposals that

option when mprior != 0, and Unif over 0,...,M
otherwise
switched back to Ellik.norm for bmonomvn.Rd examples
now tallying lpost in the traces of blasso regressions
within bmonomvn
added plot.monomvn which currently only supports
visualization of the variance of mu and S under the
Bayesian posterior (bmonomvn), and samples from the QP
solutions; see below
added structures for calculating the mean and variance
of mu and S to accomodate the MAP versions of the same
added the ability to sample from the posterior
distribution of the solution to a Quadratic Program
based on (samples) of mu and Sigma

now using unbiased cov calculations which has led to
improved performace (drastically in some cases)
added the "factor" method option to do monomvn style
(known) factor based estimates of mu and Sigma
switched back to Ellik.norm for monomvn.Rd examples
1.4 (20 July 2008)
---
removed need to store XtX in blasso explicitly, relying
instead on A and Xtx_diag
added economy option to bmonomvn to save on storage
when running several (thousand) blassos, as would
happen for large ncol(y)
precomputing full Xnorm and X (normalized) in the
Bonomvn module so that it doesn't need to be duplicated
(in smaller chunks) within all Blasso modules
corrected the bn0 summary.blasso calculation to use
the right sampling (-burnin) range and denominator
made regression traces in bmonomvn be stripped down
"blasso" class objects so that the blasso methods like
print and summary can be used
made thinning level dynamic in bmonomvn, depending on
the regression model (i.e., lasso) and RJ
smaller examples throught (b)monomvn for faster R CHECK,
and smaller final blasso example comparing to ML lasso
added parsimonious method for generating random mu and
S within the randmvn function
Ridge regression implemented as a special case in the
blasso function (added bridge function as more direct
interface)
lambda2 now walks under the prior when m=0 under lasso,
but not under ridge; fixed s2 to use Jeffrey's prior
ecaluation in log_posterior
added code to check for monotone pattern in bmonomvn
that will provide the indicator matrix needed for
monotone data augmentation in a later version
added Ellik.norm function to calculate the expected
log likelihood of an estimated normal distribution
relative to the true but don't actually use it
replaced code in the documentation files to use a new
rmse.muS function as a metric for comparison instead
of kl.norm
1.3-1 (19 June 2008)
-----
added cleanup feature to allow interupts within C code
to blasso and bmonomvn
also fixed a bug involving reading in the traces of
bmonomvn regressions
RJ models start in 90% saturate model now, instead of
100% saturated
added the ability to specify starting mu, S and lambda
values for bmonomvn (where appropriate)
now extracting lambda from lars and ridge methods for
use as starting values in bmonomvn
now providing estimats of the variance of the estimates
for S, via the output S.var
added batch option to monomvn function in order to
force a regression for each column (when FALSE)
1.3 (9 June 2008)
---
added calculations of log posterior in blasso
added reversible jump (RJ) variable selection where
proposals come from "full updating" a la Brooks & Ehlers.
This directly effects the Bayesian Lasso -- adding a
new RJ option among others. Of course, this method is
now available to the bmonomvn algorithm as well
added trace plots to plot.blasso for s2 and lambda2
in addition to new model order option "m" when RJ=TRUE
changed lamnda2 default prior setting from (r,d)=(1,1)
to (2,0.1) to avoid singular regressions when RJ is used
with the improper s2 prior with (a,b)=(0,0)
changed the way bmonomvn and blasso take many of its
hierarchical prior arguments
1.2 (8 May 2008)
---
fixed syntax errors in the documentation files and filled
out the INDEX file
Implemented Bayesian Lasso version resulting in a new
function called bmonomvn. A standalone interface to

-----
summary.monomvn now calculates the number of zeros in
the covariance matrix (& inv covar matrix) when using the
lasso method -- for summarizing pairwise marginal (and
conditional) independence
a new plot.summary.monomvn function makes histograms of
the numbers of zeros in each column of the covariance
matrix and its inverse
kl.norm now returns Inf with a warning if there is a
truly non-positive definite matrix
increased minimum (m) number of observations in rmono

method -- have emailed Hastie

lower bound for lambda when p>n
added validation="Cp" for Mallows Cp method for choosing
the best lars model
1.1: (13 Aug 2007)
----
added lars package support for lasso, etc; ridge
regression does not seem to work for the big-p small-n
problem
