Age	Commit message (Collapse)	Author	Files	Lines
2019-10-31	Add likelihood ratio test and other methods, fixes	Johannes Ranke	1	-35/+12
	The likelihood ratio test method is lrtest, in addition, methods for update and residuals were added.
2019-10-28	Fix the cutoff for likelihood based intervals	Johannes Ranke	1	-59/+44
	The cutoff now matches what is given by Venzon and Moolgavkar (1988). Also, confidence intervals closely match intervals obtained with stats4::confint in the test case where an stats4::mle object is created from the likelihood function in one test case. Static documentation rebuilt by pkgdown
2019-10-26	Address some check and test failures	Johannes Ranke	1	-3/+3

2019-10-26	parms and confint methods	Johannes Ranke	1	-33/+116
	The confint method can do profile likelihood based confidence intervals!
2019-10-21	Improve tests, remove geometric_mean	Johannes Ranke	1	-13/+2

2019-10-21	Refactor mkinfit, infrastructure work	Johannes Ranke	1	-0/+51
	mkinfit objects now include an ll() function to calculate the log-likelihood. Part of the code was refactored, hopefully making it easier to read and maintain. IRLS is currently the default algorithm for the error model "obs", for no particular reason. This may be subject to change when I get around to investigate. Slow tests are now in a separate subdirectory and will probably only be run by my own Makefile target. Formatting of test logs is improved. Roundtripping error model parameters works with a precision of 10% when we use lots of replicates in the synthetic data (see slow tests). This is not new in this commit, but as I think it is reasonable this closes #7.
