# "[WRONG CALCULATION?] Linear Regression Output"

Hi guys,

I'm a new user of RapidMiner and a newbie in data mining.

I try to built a linear regression model and compared the result it with R.

I quite shock when I get a different result from R for Std. Error and t value.

I have change feature selection to: none and ridge to 0

Is there anybody can help me to explain it?

Am I wrong to read the output?

Below is result from RM

Attribute: AGST

Coefficient: 0.635

Std. Error: 0.031

Std. Coefficient: 0.026

Tolerance: 1

t-Stat: 20.221

p-Value: 0

Result from R

AGST

Estimate: 0.6351

Std. Error: 0.1509

t value: 4.208

Pr(>|t|): 0.000335

I think we can use any data as dataset and compare the linear regression result with another statistic software.

I'm afraid the problem is in how RapidMiner do the calculation for Standard Error and t-Stat

I want to attached my dataset but don't know how to attach my file.

3Contributor II have tried using vector linear regression as you suggested but the problem is not in the coefficient. The problem is not in the coefficient but in Std Error, T Stat and P-Value.

Have you try to compare the output result (Std Error, T Stat and P-Value) from RapidMiner and another Statistic package?

Anyway how to upload a dataset?
