ptdata.removal: Simulated removal observer point count data

In mrds: Mark-Recapture Distance Sampling

Simulated removal observer point count data

Description

Simulated removal observer point count data with detection p(0)=0.8; hn sigma=30; w=100 for both observers with dependency y>0, gamma=0.1

Format

The format is 408 obs of 6 variables: distance: numeric distance from center observer: Factor w/ 2 levels "1","2": 1 2 1 2 1 2 1 2 1 2 ... detected: numeric 0/1 person: Factor with 2 levels A,B pair: Factor with 2 levels "AB" BA" object: sequential object number

Examples

data(ptdata.removal)
xx <- ddf(mrmodel=~glm(formula=~distance),
          dsmodel = ~cds(key="hn", formula = ~1),
          data = ptdata.removal, method = "rem",
          meta.data = list(point=TRUE))
summary(xx)
plot(xx,main="Simulated point count data")
