[Openspace] reduction of OLS model in Geoda

[Ola Claësson]

Hi everyone! 
 
On what basis should one reduce a OLS regression model in Geoda. I am studying infant and child mortality in sweden during the eighteenth and nineteenth century, using data on parish level. As independent variables I have, population denisty, distance to highway etc. I start out with running an ordinary OLS with all possible variable. However, when reducing such model before running a spatial or an error model, what premises shall I base the reduction on? akaike? Schwarz? R2? significance of the independent variables? 
 
sincerely
