Changes in version 0.2 There are a few changes that breaks backwards compatibility: - The 'sar' argument has been renamed to 'prob' in all distribution functions. Using the sar argument still works, but it will give a warning, and will be removed in future versions. The reason is to conform to the more precise terminology of calling the parameter "transmission probability"" rather than "secondary attack rate". - In the output from estimate_sar() the point estimate is now prob_hat, not sar_hat. New functionality: The Longini-Koopman model. - Distributon function: dchainbinom2 - Estimate parameters with estimate_sar() function, set model = 'lk'. Changes in version 0.1.5 (2024-05-27) - Initial CRAN submission.
