Re: [R-sig-Geo] Autologistic regression

Dear List,I want to learn Auto logistic regression in R. Do any one of you have a spatial data with binary response that I can use to learn it. If you have the one not used yet, that will be just awesome, if not, let me use the data set that you used, and I will not misuse it.Thanks,Mitra..

Re: [R-sig-Geo] SAR, CAR and autlogistic models

Sorry: I put wrong subject in my previous mail..Dear list,I have a data set with 3 columns (crop yield, temperature, precipitation). I fitted CAR and SAR model using yield as dependent variable and the rest two as independent variables. Now, does it make sense if I include the interaction term

Re: [R-sig-Geo] finding CRS from latitude/longitude

Dear list,I have a data set with 3 columns (crop yield, temperature, precipitation). I fitted CAR and SAR model using yield as dependent variable and the rest two as independent variables. Now, does it make sense if I include the interaction term temperature*precipitation as well as a predictor

[R-sig-Geo] interpreting SAR and CAR outputs

Hi, when I run CAR or SAR model (yield~temperature+precipitation)and I get a small p value,(SAR and CAR output given below) I reject null hypothesis concluding that there is significant spatial correlation in the residuals. What does this mean in terms of our actual data and variables(yie

[R-sig-Geo] Interpretation of simultaneous and conditional autoregressive models

Hi,i have a data set and I modeled the response, Y~X1+X2 (where Y=yield, X1=temperature, X2=Precipitation) using SAR and CAR models.. Under both models, it seems that there is significant spatial correlation in the residuals because the estimated value of lambda is 0.12087 and the p-value of th

[R-sig-Geo] HI

Dear all,In my spatial modeling of SAR, I got an error. I found that nrow(data)[1] 66length(SD_queenW$neighbours)[1] 67I am sure that my state has 66 counties. How can fix this problem? Any help ion this regard would highly be appreciated.Thanks Mitra DevkotaBrookings, SD 57006571 242 6140"
