# linear regression: strange values

Hi all,

I have a database. I have conducted a linear regression with Gretl, R, Orange data mining and RapidMiner.

I get the same results with Gretl, R, Orange data mining but RapidMiner gives me very strange results.

Look at std error, p-value and t-value.

Is this a bug ?

66Contributor II1,869Unicorncan you describe what is strange about the results? If I compare the RapidMiner results it to the results above it, I see no significant differences.

Best regards,

6Contributor IIIt seems that the correct value for std error is 2.73 and no 2.222

for the t-value 0.356 and no 0.438

for the p-value 0.723 and no 0.667

These are significant differences

In RapidMiner, are these values calculated in the usual way? If so, the results should be the same, no?
