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).

gcvals(k, k_se, k_p, n0, n0_se, n0_p, r, r_se, r_p, sigma, df, t_mid, dt, auc_l,
  auc_e, note)

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

An object of class gcvals.
