public LogisticGrowth(double N0,
                      double r,
                      double c)

public void setShape(double value)
```
  - getShape
```
public double getShape()
```
  - setTime50
```
public void setTime50(double time50)
```
    An alternative parameterization of this model. This function sets the time at which there is a 0.5 proportion of N0.
  - getDemographic
```
public double getDemographic(double t)
```
    Gets the value of the demographic function N(t) at time t.
    
    Specified by:
    
    getDemographic in interface DemographicFunction
    
    Overrides:
    
    getDemographic in class ExponentialGrowth
    
    Parameters:
    
    t - the time
    
    Returns:
    
    the value of the demographic function N(t) at time t.
  - getIntensity
```
public double getIntensity(double t)
```
    Returns value of demographic intensity function at time t (= integral 1/N(x) dx from 0 to t).
    
    Specified by:
    
    getIntensity in interface DemographicFunction
    
    Overrides:
    
    getIntensity in class ExponentialGrowth
  - getInverseIntensity
```
public double getInverseIntensity(double x)
```
    Returns value of demographic intensity function at time t (= integral 1/N(x) dx from 0 to t).
    
    Specified by:
    
    getInverseIntensity in interface DemographicFunction
    
    Overrides:
    
    getInverseIntensity in class ExponentialGrowth
  - hasIntegral
```
public boolean hasIntegral()
```
    Description copied from interface: DemographicFunction
    
    returns whether an analytical expression for the integral is implemented
    
    Specified by:
    
    hasIntegral in interface DemographicFunction
    
    Overrides:
    
    hasIntegral in class ConstantPopulation
    
    Returns:
    
    a boolean
  - getIntegral
```
public double getIntegral(double start,
                          double finish)
```
    Description copied from class: ConstantPopulation
    
    Calculates the integral 1/N(x) dx between start and finish. The inherited function in DemographicFunction.Abstract calls a numerical integrater which is unecessary.
    
    Specified by:
    
    getIntegral in interface DemographicFunction
    
    Overrides:
    
    getIntegral in class ConstantPopulation
