VERSIONS LAM 0.6  |  2022-05-17  |  Last: LAM 0.6-19
------------------------------------------------------------------------

NOTE  * new release on CRAN because LAM was removed due to
        the removal of the dependent CDM package from CRAN

------------------------------------------------------------------------
VERSIONS LAM 0.5  |  2020-05-09  |  Last: LAM 0.5-15
------------------------------------------------------------------------

NOTE  * changed computation of standard errors in pmle(). Now included
        just the likelihood part.
NOTE  * changed Metropolis-Hastings algorithm in amh() for handling boundary
        constraints

DATA  * included/modified datasets: ---
EXAMP * included/modified examples: ---

------------------------------------------------------------------------
VERSIONS LAM 0.4  |  2019-05-06  |  Last: LAM 0.4-17
------------------------------------------------------------------------

NOTE  * changed default optimizer in pmle() to "nlminb"
ADDED * added function clpm_to_ctm() for transformation of path 
        coefficients to different time intervals for cross-lagged
        panel model (due to a discussion with Steffani Sass)

DATA  * included/modified datasets: ---
EXAMP * included/modified examples: clpm_to_ctm (1,2,3)

------------------------------------------------------------------------
VERSIONS LAM 0.3  |  2018-06-06  |  Last: LAM 0.3-48
------------------------------------------------------------------------

ADDED * included Rcpp implementations for loglike_mvnorm() and
        loglike_mvnorm_NA_pattern() functions
NOTE  * optimization function stats::nlminb() can be used in
        the pmle() function as an alternative to stats::optim()
NOTE  * added 'numDeriv' package to the list of imported packages
NOTE  * included argument 'proposal_equal' in amh()
NOTE  * set the argument 'prior=NULL' as the default in pmle()
ADDED * included argument 'model_grad' in pmle() which allows the 
        specification of the gradient of the log-likelihood function

DATA  * included/modified datasets: ---
EXAMP * included/modified examples: amh (1)

------------------------------------------------------------------------
VERSIONS LAM 0.2  |  2018-03-20  |  Last: LAM 0.2-9
------------------------------------------------------------------------

ADDED * included function suff_stat_NA_pattern() which computes sufficient
        statistics for a given dataset with missing response patterns
ADDED * included function loglike_mvnorm_NA_pattern() which computed
        the multivariate normal log-likelihood for data with missing
        response patterns
NOTE  * fixed a problem with only one phase for tuning proposal distribution

DATA  * included/modified datasets: ---
EXAMP * included/modified examples: suff_stat_NA_pattern (1),
        loglike_mvnorm (2)

------------------------------------------------------------------------
VERSIONS LAM 0.1  |  2017-11-24  |  Last: LAM 0.1-22
------------------------------------------------------------------------

NOTE  * added Example 3 in amh() which was transferred from the 'STARTS'
        package to the 'LAM' package

DATA  * included/modified datasets: ---
EXAMP * included/modified examples: amh (3)

------------------------------------------------------------------------
VERSIONS LAM 0.0  |  2017-05-11  |  Last: LAM 0.0-17
------------------------------------------------------------------------

ADDED * moved amh(), loglike_mvnorm(), mlnormal() and pmle() functions 
        from 'sirt' package to 'LAM' package
NOTE  * included value acceptance_rates_history() in amh() containing
        acceptance rates of parameters during burn-in phase

DATA  * included/modified datasets: ---
EXAMP * included/modified examples: ---
