fix regression confidence interval, clean up confidence interval api #8

Closed erikbern closed 6 years ago

erikbern commented 6 years ago

it was kind of poor for various reasons

  1. was using the nonstandard 5-95% rather than 2.5-97.5%
  2. confidence_interval is really long, let's just do ci instead
  3. the confidence intervals for the regression model was wrong, i was confusing variance with standard deviation
