# 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).

### Usage

1 2 |

### 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.
