- Fixed bug in
`pinvgamma`

(`lower.tail`

and`log.p`

didn’t work) - Fixed underflow issues with
`rmnom`

and`rdirmnom`

(#7) - The
`*nst`

functions are now deprecated and renamed to more informative abbrevation`*lst`

- Now consistently with base R only the first elements of the logical arguments are used (thanks to #5)
- Fixed bug in
`rtnorm`

(sampling from lower bound returned incorrect values) - When computation becomes slow, now
`pbnbinom`

,`pbbinom`

,`pgpois`

functions are easier to brake - Automatically registering native routines via Rcpp
- Fixed bug in
`pinvgamma`

(it returned non-zero probabilities for q < 0)

- Now
`rmnom`

and`rdirmnom`

(issue #3) do not return`NaN`

’s due to underflow issues - Fixed bug (issue #4) that resulted in hanging R if zero-length vectors were provided as input

- Random generation from categorical distribution parametrized by log-probabilities
`rcatlp`

- Re-parametrized beta distribution is now more flexible since “prior” parameter was introduced (see documentation); this change is connected to switching to different prior equal to zero (instead of one as previously). Such parametrization is more commonly used in the literature. This change is documented in the
`?PropBeta`

documentation - Improvements in documentation and examples
- Fixed bugs in
`pbbinom`

,`pbnbinom`

,`pgpois`

,`*nhyper`

that prevented compiling on RedHat Linux (#2)

- Switched to C++11, underlying code was simplified and improved
- Using memoization techniques for
`pbbinom`

,`pbnbinom`

,`pgpois`

and negative hypergeometric distribution that lead to major speed improvements - Improved and simplified code for beta-binomial, beta negative-binomial, and gamma-Poisson cdf; now recursive algorithm employing memoization techniques is used what noticeably improves performance
- Discrete gamma, shifted Gompertz (d,p,r), negative hypergeometric and truncated binomial distributions (d,p,q,r) were added
- Now
`lower.tail`

and`log.p`

options for`pbetapr`

work properly - Simplified code for multivariate hypergeometric, multinomial, Dirichlet-multinomial and categorical distributions
- Truncated poisson distribution is now parametrized by lower and upper truncation points
- Fixed bugs in
`dbvpois`

(it returned underestimated probabilities),`dslash`

(there was discontinuity at x=0),`pcat`

(randomly it broke if x was greater then the upper limit), and`pdnorm`

. - Random generation functions throw warnings and produce
`NA`

’s on`NA`

’s in parameters or incorrect parameters - as in base R - Order of parameters in discrete Laplace distribution was changed to location and scale (vs scale and location) for consistency with other distributions (e.g. continous Laplace)
- Improved exception handling

- Corrected and simplified documentation for
`*prop`

distribution - Categorical, multinomial, mixture of normals and mixture of Poisson distributions are now
*less restrictive*about probability parameters and accept any non-negative values. Probability parameter vectors are normalized to sum to one (i.e.`c(1,1,1)`

becomes`c(1,1,1)/3`

) `NA`

’s and`NaN`

’s in input now always lead to`NA`

’s in output- Fixed bugs in
`rtnorm`

, now it properly handles sampling from extreme tails - Tests for multivariate distribution now done with tolerance
`1e-2`

- Bug fixes in
`qtnorm`

- now it works properly for non-standard truncated normal - Bug fixes for
`rmnom`

and`rdirmnom`

- now they correctly use the`prob`

parameter values - Minor improvements in
`dmvhyper`

and`dbvpois`

- Cleaned-up the documentation
- Added discrete Laplace distribution
- Faster RNG generator for Laplace distribution
- Changes to using lower level RNG functions (
`unif_rand`

,`norm_rand`

) when possible - More tests

- Documentation clean-up
- Minor improvements and simplifications in C++ code
- For
`min == max`

discrete uniform distribution behaves now as degenerate distribution

- Added Dirichlet-multinomial and beta prime distributions
- Code clean-up for categorical distribution
- Improvements in documentation and examples (e.g. bivariate Poisson, bivariate normal)
- Other minor improvements in the code

- Cleaning namespace - now mathematical functions are explicitly called from std library
- “using namespace Rcpp” was removed from all the files
- All the numerical values are now explicitly
`<double>`

’s, or casted to`<double>`

; or`<int>`

’s (for indexing) - Improvements in algorithms for discrete uniform, categorical, mixture of normal, mixture of Poisson distributions
- Improvements in discrete uniform; now it accepts only integer valued parameters
- Major C++ code clean-up

- Removed
`erf`

,`erfc`

,`inv_erf`

that are not used at this moment and caused problems when compiling on Fedora and Solaris - Minor improvements in documentation
- Added mixtures of normal and of Poisson distributions
- Added truncated Poisson distribution

- Minor changes and improvements in documention
- Truncated normal returns normal for infinite truncation points
- Added half-t, half-normal and half-Cauchy distributions
- Changed naming of data-variable from
`x`

to`q`

for CDF’s - Added inverse-CDF for discrete normal distribution, fixed random generation
- Added tests

`NaN`

instead of`0`

for`Inf`

values) - Added Birnbaum-Saunders (fatigue life) distribution
