Multiple Regression Data input

arsinha — Wed, 23 Jan 2019 17:20:52 GMT

I have the following data for Multiple Linear Regression analysis. I need to write the data into SAS. One way would be to attach each values of Y to each X values. that is for four same values of X we have different Y values. I just think there should be a way to record the y data as vectors that correspond to each X values. Since I need to plot this afterwards what problems may I face?

Dosage (X) Brain Activity (Y)

2.5 7.5 9.5 8.0 8.5

5.0 11.0 12.0 9.0 10.0

7.5 11.0 16.0 12.5 14.0

10.0 16.5 14.5 21.5 19.

Thank You,

Homework or a new ID?

BallardW solution shows how to read the data in and to do the regression.
If you want an indicator for the measurements, don't drop the I variable as in that data.

This seems to be the 2nd time I have seen this data set, in which case I provided the code to read in the data at
