The data used for the analysis and its metadata can be found in the dataset folder. The entire code has been provided here can be used in the latest version of SAS to run replicate various operations provided and see the various outputs generated. A detailed explanation of the various operations and the interpretation of the outputs can be found in the project report.

Code Examples

Some examples of usage:

/*Investigating Product type = Razor Blades*/
proc freq data=a4;
where product_type = 'RAZOR BLADE';
table L2*product_type;
run;

proc freq data=a4;
table product_type;
run;

data a4;
set a4;
drop product_type;
run;

data a4;
set a4;
if L2 = 'CARTRIDGES' then type = 0;
else type = 1;
run;

proc format;
value type 0 = 'Cartridges';
value type 1 = 'Disposable';
run;

/*Running Logistic Regression*/
/*Using data=L1*/
proc print data=L1 (obs=10); run; quit;

/*Testing for Non-linearity*/
data L1;
set L1;
total_weightedprice2 = total_weightedprice*total_weightedprice;
run;

data L1;
set L1;
vol_eq2 = vol_eq*vol_eq;
run;

/*Business Logistic Regression*/
title1 'Refining Business Logistic Regression for Loyalty using Stepwise Selection';
proc logistic data=L1 outmodel=betas1 desc;
	class outlet agm agf ethnicity status inc_status marital kids status / param=ref;
	model loyal_customer = outlet agm agf ethnicity status inc_status marital kids status / selection=stepwise slentry= 0.3 slstay=0.2 expb;
    output out=preds predprobs=individual;
run;

/*k-means clustering*/
/*the difference between hierachical - k-means is an iterative o(n) operation; hierachical is looking based on distances o(n2) operation*/
/*proc fastclus data=clus3 maxclusters=3 maxiter=20 list;
id panid;
var recency_score frequency_score monetary_score;
run;

proc fastclus data=clus3 maxclusters=4 maxiter=20 list;
id panid;
var recency_score frequency_score monetary_score;
run;

proc fastclus data=clus3 maxclusters=5 maxiter=20 list;
id panid;
var recency_score frequency_score monetary_score;
run;*/
