segmentation in dsm

[Olga Lyashevska]

Hi all, 

I noticed that depending on segment size there are more or less 0's introduced to the dataset and I would like to fit a model using data as it is, i.e. with no segment size effect.

So I have 2 questions:

1. Can I fit dsm without segmenting data?

2. If not, can I make segment size equal to transect and in this way override its effect?

Many thanks for your help,

Olga

Afraid you cannot fit a density surface model without segmenting.  The number of replicate transects would be too few to construct a model that provided much information about spatial distribution of organisms.  I suppose you could make segment length equal to transect length, but as I say, the number of data points for the spatial model would be very small and the spatial scale of the measured covariates would be inconsistent with the transect lengths.

Thanks Eric, I appreciate that!
