Synopsis The 95% slope confidence interval.
Function
num slopeConfidenceInterval(lrel[num,num] values) throws IllegalArgument(value v, str message)
Usage
import analysis::statistics::SimpleRegression;
Description Returns the half-width of a 95% confidence interval for the slope estimate.
The 95% confidence interval is
(slope - slopeConfidenceInterval, slope + slopeConfidenceInterval)
(slope - slopeConfidenceInterval, slope + slopeConfidenceInterval)
Pitfalls The validity of this statistic depends on the assumption that the observations included in the model are drawn from a
Bivariate Normal Distribution
