• Linear Regression
The regression formula for linear regression is:
y = A+Bx.
• Example: Atmospheric pressure vs. Temperature
Temperature
Enter REG mode (Linear Regression)
Atmospheric
pressure
Perform linear regression to
determine the regression
formula terms and correlation
coefficient for the data nearby.
Next, use the regression
formula to estimate
atmospheric pressure at 18º
and temperature at 1000 hPa.
