A confidence interval is a range of valuesthat encloses a parameter with a given likelihood.So let’s say we’ve a sample of 200 people from a population of 100,000. Our sample data come up with a correlation of 0.41 and indicate thatthe 95% confidence interval for this correlationruns from 0.29 to 0.52.This means that the range of […]
What’s this about? We call them ERMs—extended regression models. There are four new commands that fit linear models linear models with interval-censored outcomes, including tobit models probit models ordered probit models with any combination of endogenous covariates sample selection nonrandom treatment assignment, both exogenous and endogenous Here are some of the features in discipline-specific terminology: […]

What’s this about? We believe that there are groups in our population and that individuals in these groups behave differently. But we don’t have a variable that identifies the groups. The groups may be consumers with different buying preferences, adolescents with different patterns of behavior, or health status classifications. LCA lets us identify and understand […]
What’s this about? Nonparametric regression, like linear regression, estimates mean outcomes for a given set of covariates. Unlike linear regression, nonparametric regression is agnostic about the functional form between the outcome and the covariates and is therefore not subject to misspecification error. In nonparametric regression, you do not specify the functional form. You specify the […]
