Next, use the regression formula to estimate atmospheric pressure at -5°C
and temperature at 1000 hPa. Finally
, calculate the coefficient of
determination (r
2
) and sample covariance (
∑
xy - n ∙ x
-
∙ y
-
n - 1
).
In the REG Mode:
(Lin)
(CLR) (Scl) (Stat clear)
Each time you press to register your input, the number of data input up
to that point is indicated on the display ( n value).
