Please could you help me (or direct me to someone who can help me) with the following:

I have a spreadsheet with a number of environmental independent variables (e.g. slope, radiation, etc.) with dependent variables (presence absence and densities of two plant species Ls and Ee). MY INDEPENDENT VARIABLES ARE IN CATEGORIES AND ARE THUS NOT CONTINUOUS.

I have looked at the help option in STAThelp in my Statistica v.9.1 but it seems as though my data is formatted differently and I am unsure of my results.

Please could you help me with the following:

1. Determining any collinearity between the indepedent variables.

2. Logistic regression for fire, Ls and Ee presence/absence

3. Multiple regression for Ls and Ee densities?

Your help in this regard will be much appreciated!

Kind regards,

Andrew
