y = b*m^x
Calculate the correlation, m factor, b factor and estimates for the following data:
X | Y |
2 | 33 |
3 | 42 |
4 | 54 |
5 | 64 |
6 | 77 |
Value | Key | Display | Description |
---|---|---|---|
shift C lists | 0 | Clears the x and y lists. | |
33 | = (CHN, ALG) or ENTER (RPN) | 33.0000 | Enters y value. |
2 | Σ+ | 1.0000 | Append x and y to lists x and y. |
42 | = or ENTER | 42.0000 | Enters y value. |
3 | Σ+ | 2.0000 | Append x and y to lists x and y. |
Repeat for the remaining data. |
Data can be verified and corrected using the List Manager.
