Correlation Between Independent and dependent variables

Mushy — Sun, 09 Jun 2024 06:35:02 GMT

Hello ,

How could i find dependency/importance/weightage between Dependent variables in SAS?

Example:

Var1 Var2 Result

1 2 5

3 2 7

in the above example weigtage of var2 is higher because the formala is result=var1+2var2

Thanks,

Mushy

The first step for you question is summary statistic by exploring scatter plot.

proc sgscatter data=sashelp.heart(obs=100);
matrix height weight Diastolic Systolic/ellipse diagonal=(histogram);
run;

I find this confusing sequence of statements. I am not sure what you want.

You start by asking about correlation between independent and dependent variables in the subject line, and then only talk about dependent variables "How could i find dependency/importance/weightage between Dependent variables in SAS?"

You state the fact "in the above example weigtage of var2 is higher because the formala is result=var1+2var2" but this isn't a question; what is the relevance of this?

Your question is not clear, but if you are asking how to assess the relative importance of predictor (independent) variables in a model on a response (dependent) variable, then see this note.

@StatDave @Ksharp @PaigeMiller Thanks for the response. Your posts helped me to explore the statistics graph and used different procs for dependency check.

I'm not sure what your may be thinking about asking with correlation but if I build a data set with your formula for some data and run a regression:

data examine;
  do x1= 1 to 25;
     do x2 = -5 to 5;
        result = x1 + 2*x2;
        output;
      end;
   end;
run;

proc reg data=examine;
   model result=x1 x2;
run;

The coefficient for X2 is that "weight"

Parameter Estimates
Variable	DF	Parameter Estimate	Standard Error	t Value	Pr > \|t\|
Intercept	1	0	0	.	.
x1	1	1.00000	0	Infty	<.0001
x2	1	2.00000	0	Infty	<.0001
