Dear All:

I was and I am teaching sampling techniques class. I do need some help with complex survey analysis.

Variables:

stratum1 (1,2)
months (0,1,2)
x1 (1=yes, 2=no) ---- categorical
x2 --- continuous
weight1 ---- the weight variable used in the analysis



I  need help with how to:


(1) get estimates for the mean for each month (0,1,2) --- the variable X2 

(2) get estimates for the proportion of ones for each month (0,1,2) --- the variable X1 

(3) do ANOVA test and multiple comparison test on means month0, month1, and month2

(4) perform chi-squares test for the equality of proportions in the 3 months.

(5) test for trend (increasing or decreasing of proportions and means over months)

Below is the data set (part of the data set). If you like me to send you the whole data set, please let me know, and I will send it by email. It is small file. the full data has 11 months (0,1,2,...,10).

I really thank you all very much for your helps

Abou
