Source:`R/breathtest_parameters.R`

`tlag_bluck_coward.Rd`

This parameter is probably not very useful, as it can be negative

## Arguments

- cf
named vector of coefficients; only

`k`

and`beta`

are required. Note that in this package,`k`

is measured in 1/min (e.g. 0.01/min), while in the literature is is often quoted as 1/h (e.g. 0.6/h).

`exp_beta`

, and `t50_bluck_coward`
