time |
Time in seconds. |
parentFraction |
Measured values of parent fraction. |
fit_ppf0 |
Should the starting plasma parent fraction be fitted? Otherwise, it is set to 1. Defaults to FALSE. |
fit_delay |
Should the delay of the plasma parent fraction be fitted? Otherwise, it is set to 0. Defaults to FALSE. |
lower |
Named list of the lower limits. |
upper |
Named list of the upper limits. |
multstart_lower |
Named list of the lower starting limits. |
multstart_upper |
Named list of the upper starting limits. |
multstart_iter |
Number of fits to perform before deciding on an optimal. |
An nls fit object.
