## Working with Numbers generated from Regression Output

 Hi, I have a query on regression output generated by R. > result=lm( Y~X , data=trail) > summary(result) After running this 2 statements the following output is generated. Call: lm(formula = Y ~ X, data = trail) Residuals:     Min      1Q  Median      3Q     Max -245.30  -90.77  -30.30   54.99  532.78 Coefficients:             Estimate Std. Error t value Pr(>|t|) (Intercept) 245.2982    62.1307   3.948 0.000376 *** X             0.5192     0.1752   2.963 0.005533 ** --- Signif. codes:  0 *** 0.001 ** 0.01 * 0.05 . 0.1   1 Residual standard error: 169.1 on 34 degrees of freedom Multiple R-squared: 0.2052,     Adjusted R-squared: 0.1818 F-statistic: 8.777 on 1 and 34 DF,  p-value: 0.005533 >From this output, I intend to use the beta values to calculate elasticities. Is this possible directly in R? If not, then when I paste this output in Excel, It is pasted as an image, and thus I cannot use the beta values for calculating any other metric. Can anyone please help me out!!!

## Re: Working with Numbers generated from Regression Output

 You can learn a lot from the help files.  Check out the help files for the lm() and summary.lm() functions ?lm ?summary.lm You can extract the beta values in a few different ways. These two will give you just the estimates in a vector: coef(result) result\$coef These two will give you the estimates and more in a matrix: coef(summary(result)) summary(result)\$coef Jean Krunal Nanavati <[hidden email]> wrote on 07/26/2012 07:28:02 AM: > > Hi, > > I have a query on regression output generated by R. > > > result=lm( Y~X , data=trail) > > summary(result) > > After running this 2 statements the following output is generated. > > Call: > lm(formula = Y ~ X, data = trail) > > Residuals: >     Min      1Q  Median      3Q     Max > -245.30  -90.77  -30.30   54.99  532.78 > > Coefficients: >             Estimate Std.

 In reply to this post by Krunal Nanavati Check str(lmobj).  You can see the underlying structure of lm object.  It is actually a list.  You can access its individual components with \$ operator. Bye
