Fix issue #64.
estimate_errors()
is decomposed intostandard_errors()
,margin_errors()
andestimate_errors()
.standard_errors()
andmargin_errors()
will return standard errors and margin of errors, whileestimate_errors()
will print out standard errors, margin of errors and confidence intervals. What the presentestimate_errors()
does is equal tomargin_errors()
.The
alpha
parameter should be defined as significance level to reduce ambiguity and therefore usequantile(dist, 1 - alpha/2)
to find (two-sided) critical values. Present version ofestimate_errors(fit, alpha=0.95)
is actually finding 90% confidence interval if I'm understanding the code correctly.
