    Comparing three different slopes between three regression lines

    oh I just noticed the sketch I did is not good! it should be three different treatment so in green its y=b2x+a2

    Comparing three different slopes between three regression lines

    The cells were a mixture from few mice that went through the same conditioning and after separated for three groups randomly the treatment applied

    Comparing three different slopes between three regression lines

    Treatments were assigned randomly. It's a basic science experiment in which I took cells from mice and put them through 3 different treatments and then checked one of their function (the y axis) in different time periods. every 30 minutes I checked for the groups. I expected the treatment to...

    Comparing three different slopes between three regression lines

    Hi all, I hope the thread is in it's place. I wanted to compare slopes between three different simple regression lines. The three data sets have the same x (time) and y (measured value) variables but each data set have gone through a different treatment and so the intercept and the slopes are...

    Comparing three coefficients
