OPTIONS> CUERATE Syntax: CUERATE = value1 /SE=value2 ; Description: For cue counting (pg:8-9, 270-275), 'value1' is the average rate at which animals issue visual or auditory detection cues. The rate should be given in the same units of time as the values given for sampling effort in the data. For example, if effort is measured in hours then the cue rate should be number of cues per hour. The cue rate must be a positive number (>0). Optionally a standard error for the cue rate can be given with 'value2'. This standard error is accounted for in the estimated standard error of the density and abundance estimates. This option is only used if TYPE=CUE is specified. Default: CUERATE=1/SE=0; Example: An estimate of the cue rate is 12 per hour with a standard error of 2 per hour. The sample effort for this cue counting example be specified in hours sampled. CUERATE=12 /SE=2 ; DEFAULT Syntax: DEFAULT ; Description: This command resets all of the options to their default values. Remember that an option remains in effect until it is changed or DISTANCE is terminated. The default values for each of the options are: PVALUE=0.15 SELECT=SEQUENTIAL MAXTERMS=5 ITERATIONS=100 LOOKAHEAD=1 EPSILON=1.0E-7 PRINT=SELECT SQUEEZE=OFF BOOTSTRAPS=1000 SEED=0 SF=1 CUERATE=1/SE=0 24 TYPE=LINE OBJECT=SINGLE DISTANCE=PERP/EXACT/UNITS=METERS LENGTH/UNITS=KILOMETERS AREA/UNITS=HECTARES
