MULTREG2 performs multiple linear regressions on data sets stored as lists in the TI-84. It provides essentially the same operations as the Stats-List Editor on TI-89's:

• Determines a linear regression from input lists.
• Calculates basic statistics like the correlation coefficient, the coefficient of determination, the F-score and its P-value, and the standard error of estimate.
• Calculates coefficient statistics like the coefficient standard errors, their corresponding T-scores and P-values.
• Provides predicted values with predicted confidence intervals for a given set of inputs

Anyone taking a Statistics class without a TI-89 or better (or equivalent computer software) will find this tool useful.
