And more new features
We wish we had the space to tell you more about the following. Visit stata.com/new-in-stata. You can read more, and even read the manual entries and worked examples.
More than 2 billion observations are allowed by the multiprocessor version of Stata, Stata/MP. You are limited only by memory.
Tests for structural break in time series let you test after estimation for a break at known or unknown dates.
Hurdle model estimation allows you to model censored and uncensored outcomes in separate equations; uncensored outcomes are observed when a hurdle is cleared.
Censored Poisson regression lets you model count processes with values that are not observed below a threshold, not observed above a threshold, or both simultaneously.
Sampling weights allowed with treatment effects is highly requested, so now Stata allows it.
Integrate better with Excel® by using Stata to insert graphs, formulas, formatted text, and more.
Stata's interface can now be in Spanish or Japanese, including all menus, dialogs, and other interface elements.
ICD-10 diagnosis codes are now understood by Stata just as ICD-9 codes are.
The 64-bit Mersenne Twister now provides Stata's pseudorandom numbers, and PRNGs for more distributions are available.
Quick starts have been added to the manuals to give you a quick overview or refresher for common syntaxes.
Fractional regression lets you model variables that are fractions, proportions, or rates.
