![]() Dynamic stochastic general equilibrium (DSGE) models. And multilevel models are among them! You can now type -bayes:- in front of estimation commands to fit Bayesian regression models for over fifty likelihoods. Bayesian prefix command. Even incorporate latent classes in path models. Continuous outcomes (latent profile analysis). Nonlinear mixed-effects models. ", where the 52.4 is obtained from -e(F)-. By parts, we mean you can write a sentence such as "The F statistic is 52.4 and. You can now combine Markdown text with executable Stata code to produce web containing prose, Stata output, parts of Stata output, and graphs. Graph impulse-response functions afterward. Finite mixture models (FMMs). For when you only know a time when subjects have not yet failed and another when they have already failed. Interval-censored parametric survival-time models. Download shapefiles from the web, merge with your geographic-based data, and fit your SAR models with cross-sectional or panel data. Spatial autoregressive models (SAR). Bootstrap standard errors. Our implementation uses kernel methods. Nonparametric regression. Discrete choice models with random coefficients, meaning you can relax the IIA assumption. You mix one or more regression models using any of 17 existing estimation commands. It's now just as easy to produce Word and PDF documents as it is to produce Excel worksheets. You can now add your own power and sample-size methods too. Power analysis for cluster-randomized designs (CRDs) and for regression models. Predict derivatives or levels. These are the codes from NCHS and CMS that are mandated for all medical billing in the U.S. Now you can change them so that you can see what's underneath. Stata's colors used to be fully opaque, which is to say, not-at-all transparent. Stat Transfer 13 Series Are AvailablePanel-data tobit with random coefficients If you do, Stata can browse, search, and assemble datasets for you.I'll stop, but the following are most certainly highlights too: Louis Federal Reserve Bank. And international economic and financial time series are available to registered users courtesy of the St. Federal Reserve Economic Data (FRED) support. ![]() It also seems to ignore most if not all of the suggestions and requests made by avid stata users in this very forum. You can upgrade and still share with those who haven't.Visit our blog and our features page to learn more.I'm sorry to say that on the face of it, this looks like a very disappointing release.Most of these additions would better be charcaterized as simmilar to user addons than what I would expect from stata itself. Add your own power and sample-size methodsBy the way, Stata 15's dataset format is the same as Stata 14's. The current limit is not big enough for 2017 and many users (not in my field, btw) would not use stata due to this reason.4. Limited number of variables - while this has increased, there have been several discussions on this very forum how today's "big data" (or even "medium data") sets can have hundreds of thousands of variables. A single "flavour" that utilizes multi cores, I think, is a long time coming.3. The price differentiation between MP and non-MP flavors prevents users from utilizing the speed benefits of multi cores. No multi-core support in non-MP versions: Other stat software support multi-core (which is standard in computers now days, and has been for sometime) natively. Interface and results window: The coercive abbreviation of output (of long variable names etc.) - At least give users the ability to decide whether or not they wish to abbreviate (the infamous ~) output.2. Does visual studio for mac have mysqlPackages that a large percentage of users use daily, and that even appear on the stata FAQ. Incorporating general-use addons into vanilla stata - User addons are great, but I would have expected statacorp to work with package authors to get their packages into native stata. Debugging programs in stata is more art than sciense, with the user writing nonsense code where I want to program to stop (as it will exit due to error) just to "break" at a given time.5. If a dataset in Stata/MP 15 has anywhere between 32,768 variables and 120,000 variables, then format 119 is used. Format 118 is also used by Stata/IC 15, Stata/SE 15, and, by default, in Stata/MP 15.Format 118 uses two bytes to represent variable numbers, and as such, Stata/MP 15's new maximum of 120,000 variables is impossible to save in a format 118 dataset. Speed improvements - I see very little mentioning of "under the hood" improvements, for example - are there not still built-in stata commands which have not yet been mata-ized?Is the format of Stata datasets the same as before or has it changed?Both.Stata 14's dataset format is what we call internally '118' format, as that is the version number in its header. Working with several databases at the same time - I understand that this will mean a major shift in stata-philosophy, but since other stat software to this at ease, I see no reason for stata not to have this pretty basic feature - Instead the user has to juggle with multiple instances of stata, or keep clearing and using each dataset separately.7. Stata 14 and earlier cannot load datasets with 32,768 or more variables, so it doesn't really matter whether the format is 118 or 119 in that case - there is no way they can load a dataset of that size.In any case, the dataset format has not changed in Stata/IC 15, has not changed in Stata/SE 15, has not changed by default in Stata/MP 15, and only changes to allow larger variable numbers in Stata/MP when absolutely necessary.Finally, saveold in Stata 15 allows datasets to be saved back to Stata 11 format.
