gcvals {growthcurver} | R Documentation |
Creates an object of type gcvals.
Description
Constructor function for the "gcvals" class. This object is most often
obtained when calling SummarizeGrowth
(it is the first
parameter in the gcvals
object).

Arguments
k |
The carrying capacity parameter |
k_se |
The standard error of the carrying capacity parameter |
k_p |
The p value of the carrying capacity parameter |
n0 |
The initial population size |
n0_se |
The standard error of the initial population size |
n0_p |
The p value of the initial population size |
r |
The growth rate |
r_se |
The standard error of the growth rate |
r_p |
The p value of the growthrate |
sigma |
Residual standard error from non-linear least squares fit of the model to the data |
df |
Degrees of freedom |
t_mid |
The time at the inflection point of the logistic curve (occurs at half of the carrying capacity) |
dt |
The maximum doubling time, obtained by evaluating the the unrestrained growth of the population with growth rate r |
auc_l |
The area under the curve of the fitted logistic equation from time 0 to time t |
auc_e |
The area under the curve of the measurements. |
note |
Feedback on common problems with fitting the logistic curve to the data |
Value
