Working with Numbers generated from Regression Output

Hi Jean,



Thank you very much for getting back to me.



I tried the solutions that you have provided.



First I tried the ?coef(result) statement?.and I got the below output

coef(result)

(Intercept)            X       Volume

-30.40275264   0.57786290   0.02594024



Then, I simply selected this output from the R window, and pasted it
into
an Excel Sheet, and it go pasted in the below manner.





















(Intercept)            X       Volume















-30.40275264   0.57786290   0.02594024































































So, here all the output is getting pasted in a single cell. What I am
looking for is something different.



Here is what I am looking for















(Intercept)

X

Volume





-30.40275264

0.57786292

0.02594024



































So, once the beta values are placed in different cells, I can work on
those
numbers individually to calculate elasticities.



I tried with the other statements as well, but they are not addressing
this
issue.



Can you please help me out with this. I really appreciate your time and
effort.









Thanks & Regards,

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

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!!!
