Logistic Regression (d ƒ 0) (LogisticD)
Fits the model equation y=c(1+a*e
(
⁻bx
)
)+d to the data using an iterative least-
squares fit. It displays values for a, b, c and d.
Multiple Linear Regression (MultReg)
Calculates multiple linear regression of list Y on lists X1, X2, …, X10.

Calculating a Distribution
Example: Calculate a distribution to fit the Normal Pdf distribution model.
1. Click the column formula cell (second cell from the top) in columnA.
2. Click Statistics > Distributions > Normal Pdf to choose the Distribution
model.
The Normal Pdf dialog box opens and displays fields for typing or
selecting the arguments for the calculation.
- Press Tab as necessary to move from field to field and provide each
argument. You can type values, or select them from the drop down list:
- X Value: Click the drop-down arrow to choose any list in the problem
to provide the x values for the calculation.
- Mean: Type a value for the mean or click the drop-down arrow to
choose a variable that contains the mean.
- Standard Deviation: Type a value for the standard deviation or choose
a variable that contains the standard deviation.
3. Click the Draw check box to see the distribution plotted in Data&Statistics.
Note: The Draw option is not available for all distributions.
4. Click OK.
Lists&Spreadsheet inserts two columns: one containing the names of the
results, and one containing the corresponding values. The results are
plotted in Data&Statistics.
