Plot fitted hazard and perpendicular denisty distribution
resulting from a call of fityx
. When simulating, true hazard functions
and perpendicular density distribution can also be added to the plot.

x |
perpendicular distance observations |
nclass |
number of histogram classes |
nint |
number of intervals in numerical integration |
plot |
boolean, plot results |
addTruth |
boolean add true hazard and perp. density when simulating |
true.pi.x |
true perpendicular density distribution function used when simulating |
true.logphi |
true perpendicular density distribution function parameters used when simulating |
true.hr |
true hazard rate function used when simulating. |
true.b |
true hazard rate function parameters used when simulating. |
N |
true number of animals in simulated distribution, used to calculate bias (see details). |
fit |
return from a call of |
true.legend |
If true (and addTruth) plots legend for true functions in bottom left. |
When N
is specified, bias in estimated number of animals ,\hat N,
is calculated.
