Dear All:
I am trying to use the gstslshet function to generate the estimate the sarar
model. However, there is an error occur as following:
Error in solve.default(crossprod(reg)) :
system is computationally singular: reciprocal condition number =
4.38039e-25
Is there anyone ever
Hi,
I have a 3 bands (RGB) image and want to add to it an alpha band based
on the value of the other bands (the darker, the less transparent).
Input is: ENVI/ENVI .hdr Labelled.
QuantumGIS does not recognize the alpha band (alpha tag is not set).
When the alpha band is selected manually in Arcgis,
Hello everyone,
I am looking for a R code to simulate an spatial distribution of multinomial
classes (like colors classes) in a map.
The problem is find a a multivariate distribution of the color classes
(covariate: map colors) and a continous variable (like rain or ph) to study
different kr

Thank you both very much!
Some more details on the data: The individual roads are most of the time
represented by more than two points. The road data consists of about 80
points representing around 75000 roads.
I tried to convert it to a linnet-object, but got the error (translated):

Dear all,
I would like to implement a spatial quantile regression using instrumental
variable estimation (according to Su and Yang (2007), Instrumental variable
quantile estimation of spatial autoregressive models, SMU economics & statistis
working paper series, 2007, 05-2007, p.35 ).
I am app
