Class histNorm
- public class histNorm
- extends hist
paint
public void paint(Graphics g)
- If it sets up to fit normal distribution and total samples >2, it will draw normal distribution line
setNorm
public void setNorm(boolean norm)
- Set up the normal distribution fitting switch
fitNormal
private void fitNormal(Graphics g)
- This is private function. If normal distribution fitting is set up, it will automatically draw normal distribution line on histogram in the paint rountine.
zprob
public double zprob(double z)
- return normal distribution p(x>z) probability
MeanSd
float[] MeanSd()
- This is a private method, return histogram data set's total sample size, mean and standard deviation
