Interpreting stata data

Use the regress command to run a regression of infant birth weight(bwt) and maternal weight at last menstrual period(lwt). Interpret R² and the intercept and slope parameters from the regression model.

How can I interpret this data.. what does each variable mean especially for MS, Coef., Std. Err., T, Confidance interval

Solution

R-sqaure :

Here r-sqaure is 0.0345. It means 3.45% variabity in dependent variable (infant birth weight(bwt)) will be accounted by the independent variable (maternal weight at last menstrual period(lwt)).

Intercept:

Here inetrcept is : 2369.184

It means that if maternal weight at last menstrual period (lwt) is zero then infant birth weight(bwt) will be 2369.184. In the given situation this inetrcept does not have any meaning.

Slope:

Here slope is 4.43. It means if lwt s increase by 1 unit then bwt will be increased by 4.43 units.
