# openEBGM version history

v0.8.3

• Fixed unit testing problems caused by R’s future switch to stringsAsFactors = FALSE.

v0.8.2

• Adjusted calculation for expected counts using suggestion from Piotr Świnarski. Previously, calculation failed when marginal counts became too large for integer multiplication.

v0.8.1

• Corrected unit test failures for processRaw() resulting from base R changes to the sample() function.

• Added DEoptim::DEoptim() example to hyperparameter estimation vignette.

v0.8.0

• processRaw() now lists all strata when stratification is used.

• Added argument ‘list_ids’ to processRaw().

v0.7.0

• Added the autoSquash() function to automate data squashing.

• Changed exit condition for while loop in hyperEM(). hyperEM() now throws an error if the number of “stuck” or repeated estimates of theta exceeds 20 when using ‘method = “nlminb”’.

• Changed upper limit from 1 to 0.999 in hidden functions .updateThetaLL() and .updateThetaLLD(), which are called by hyperEM().

v0.6.0

• Changed ‘keep_bins’ formal argument in squashData() to ‘keep_pts’ for added flexibility.

v0.5.0

• Efficiency and code hygiene improvements to processRaw() and squashData().

v0.4.0

• Added the hyperEM() function to estimate hyperparameters using an implementation of the EM algorithm.

v0.3.0

• Added confidence intervals to autoHyper() and standard errors to autoHyper() and exploreHypers().

• processRaw() now returns Inf instead of 99999 when PRR results in division by zero.

• Fixed minor bug in exploreHypers().

v0.2.0

• Minor aesthetic changes to plot(), summary(), and print() methods.
• Relaxed convergence requirements for exploreHypers() and autoHyper().
