min_temp, max_temp, criterion = "D", opts = NULL, x_0 = NULL)
|
model |
character string defining the inactivation model to use. |
pars |
list defining the nominal model parameters. |
limit |
numerical value describing the maximum number of log-reductions that can be identified in the experiment limit = logDL - logN0, where DL is the detection limit. |
n_points |
numerical stating the number of data points. |
min_time |
numerical stating the lower limit for the time points. |
max_time |
numerical stating the upper limit for the time points. |
min_temp |
numerical stating the lower limit for the temperature. |
max_temp |
numerical stating the upper limit for the temperature. |
criterion |
character string defining the criterion to use. |
opts |
options for the MEIGO algorithm. By default, a maximum of 2000 function evaluations with local finish with the DHC algorithm (see help from MEIGO). |
x_0 |
initial point for the MEIGO algorithm. By default, it is NULL. |
