S-VAR

Sur une calculatrice Casio on peut appeler des variables statistiques

		2

SD mode

For standard deviation (SD mode) you can show

		2		x̅  xσn xσn-1   1  2   3

 1  = Arithmetic mean

 2  = Population

 3  = Sample

 

---

REG mode

For regression calculations (REG mode) you can show

		2		x̅  xσn xσn-1   1  2   3

 1  = (x̅): mean

 2  = (xσn): population

 3  = (xσn-1): sample

y̅  yσn yσn-1   1  2   3

 1  = (y̅): mean

 2  = (yσn): population

 3  = (yσn-1): sample

 

In case of regression calculations other than quadratic regression it shows

A  B   r     1  2   3

 1  = (A): Regression coefficient A (y-intercept)

 2  = (B): Regression coefficient B (slope)

 3  = (r): Correlation coefficient

x̂  ŷ          1  2

 1  = (x̂)

 2  = (ŷ)

 

In case of quadratic regression it shows

A  B   C     1  2   3

 1  = (A): Regression coefficient A

 2  = (B): Regression coefficient B

 3  = (C): Regression coefficient C

x̂1  x̂2  ŷ    1   2   3

 1  = (x̂1)

 2  = (x̂2)

 3  = (ŷ)
