Announcement and call for presentations

TStat, Stata’s distributor in Italy, is pleased to announce that the 8th Italian Stata Users Group meeting will take place in Venice on November 17–18, 2011. The meeting provides Stata users working in different research areas with a unique opportunity to exchange ideas, experiences, and information on user-written routines and applications. Stata users interested in contributing to the meeting are encouraged to submit their proposals to the scientific committee. As in previous years, the emphasis will be on the development of new commands or procedures currently unavailable in Stata.


Registration form in Italian.

Introduzione all’analisi dei dati multivariati con Stata (in italiano)

Obiettivo: Il corso si propone di fornire ai partecipanti un’introduzione ai metodi per l’analisi di dati multivariati attraverso l’impiego di Stata. Grazie all'enorme quantità di dati ormai disponibili in ogni settore industriale e commerciale, le tecniche di analisi statistica multivariata ricoprono oggi più mai un ruolo fondamentale per l’estrazione di utili informazioni dai dati stessi. Durante il corso saranno illustrate le principali metodologie di analisi multivariata (analisi dei cluster, analisi delle componenti principali, analisi fattoriale) attraverso esempi e casi concreti.

Destinatari: Il corso è di interesse per ricercatori/analisti che desiderino condurre ricerche empiriche utilizzando dati multivariati.

Prerequisiti: Conoscenza di base di statistica e del software Stata.

Sessione I (9:00–11:00) — I dati multivariati: Primi indicatori di sintesi e rappresentazioni grafiche

  • Tipi di variabili e il problema dei dati mancanti
  • Covarianze, correlazioni e misure di distanza
  • La distribuzione normale multivariata
  • Grafici per la visualizzazione di dati multivariati

Sessione II (11:15–1:00) — Analisi delle componenti principali e analisi fattoriale

  • Analisi delle componenti principali
    • Introduzione
    • Calcolo delle componenti principali
    • Calcolo degli scores delle componenti principali
  • Analisi dei fattori
    • Introduzione
    • Stima dei fattori
    • Scelta del numero di fattori
    • Rotazione dei fattori

Sessione III (2:00–3:45) — Analisi dei cluster

  • Introduzione agli algoritmi di clustering
  • Principali metodi agglomerativi di clustering
    • Il dendrogramma
    • Single linkage
    • Complete linkage
    • Average linkage
    • Metodo di Ward
  • Principali metodi divisivi di clustering
    • K-means
  • Profilazione dei cluster

Sessione IV (4:00–5:00) — Altri metodi di analisi dei dati multivariati

  • Estensioni degli approcci presentati
  • Altre tecniche di analisi multivariata (analisi delle corrispondenze, scaling multidimensionale, etc.)

Numero massimo di iscritti: 20
Termine iscrizione: 5 Novembre 2011

Treatments effects estimation using Stata (in English)

Presenter: David Drukker, StataCorp

Course objectives: To provide an introduction to estimators of a binary treatment effect when individuals are selected into treatment based observable variables and some randomness that is not related to any observable variable used to model the response. After providing an introduction to the potential outcome framework, we will discuss some parametric models for treatment effects estimation to gain some intuition. Then we will progressively drop many of the strong assumptions in the original parametric model and use semiparametric and nonparametric methods to estimate the treatment effect. During the course, we cover matching estimators, inverse propensity-score weighting estimators, and series estimators.

Potential audience: Researchers interested in using Stata for treatment effects estimation

Prerequisites: Familiarity with some Stata estimation commands and the English language

Session I

  • An introduction to the potential outcome framework
  • The meaning of “selection on observables”
  • Other identifying assumptions

Session II

  • Some simple parametric estimators
  • The estimation and use of the propensity score
  • Some series estimators

Session III

  • The Imbens–Abadie matching estimators

Session IV

  • Some double-robust estimators
