Stata è un software statistico completo le cui potenzialità sono in grado di soddisfare un’ampia gamma di utenti accademici e professionali, in discipline quali economia, sociologia, psicologia, biostatistica, epidemiologia e altre. Stata include una vasta gamma di funzioni statistiche (vedi la sezione principali caratteristiche) e piene capacità di data management. E’ facile da usare per utenti alle prime armi, ma allo stesso tempo offre opzioni di programmazione sofisticate per gli utenti più esperti. Nuove potenzialità sviluppate e aggiornamenti ufficiali possono essere installati semplicemente tramite internet.
Stata è disponibile in tre diverse edizioni:
- Stata/IC è ideale per le banche dati di dimensione media
- Stata/SE permette di lavorare con banche dati molto più ampie rispetto a Stata/IC mentre
- Stata/MP è la versione più veloce, in grado di sfruttare le potenzialità di PC multiprocessori, inclusi Intel i3, i5, i7 Intel CoreTM Duo e AMD X2 dual-core, Xeon, e Celeron. Consente per esempio di analizzare i dati a una velocità nettamente superiore: si risparmiano tra un terzo e la metà del tempo rispetto a Stata/SE su laptop dual-core economici e tra la metà e tre quarti del tempo su desktop e portatili con quattro core. Stata/MP è ancora più veloce su server multiprocessore; supporta processori fino a 64 core. Una velocità elevata è spesso cruciale quando si eseguono procedure di stima intensamente computazionali. Alcune delle procedure di stima di Stata, inclusa la regressione lineare, sono quasi perfettamente parallelizzate, il che significa che funzionano due volte più velocemente su una macchina con due core, quattro volte più velocemente su quattro core, e così via. E’ importante notare che alcuni comandi di stima possono essere parallelizzati più di altri. Considerandone la mediana, i comandi di stima sono 1,9 volte più veloci sulle macchine 2 core, 3,1 volte più veloci su 4 core e 4,3 volte più veloci sulle macchine con 8 core. La velocità può essere importante anche nella gestione dei dati di grandi dimensioni. L’aggiunta di nuove variabili per esempio è quasi parallela al 100%, mentre il comando di ordinamento dei dati è parallelo al 75%.
Consultare il rapporto Stata/MP per ulteriori informazioni sulle capacità e velocità della versione Stata/MP.

This section shall not apply to any information that is or becomes publicly available through no breach of this Agreement by the receiving party or is independently developed by the receiving party without access to or use of the Confidential Information of the disclosing party. The foregoing confidentiality obligations will not restrict either party from disclosing Confidential Information of the other party pursuant to the order or requirement of a court, administrative agency, or other governmental body, provided that the party required to make such a disclosure gives reasonable notice to the other party to enable the other party to seek a protective order or otherwise limit such disclosure. The receiving party of any Confidential Information of the disclosing party agrees not to use the disclosing party’s Confidential Information for any purpose except as necessary to fulfill its obligations and exercise its rights under this Agreement. The receiving party shall protect the secrecy of and avoid disclosure and unauthorized use of the disclosing party’s Confidential Information with no less than reasonable care.

Except as expressly provided herein, Customer may not assign or transfer any of its rights under this Agreement (including its licenses with respect to the Licensed Software and Documentation) without the prior written consent of StataCorp. Unless the Customer is required by statute or regulation to apply the law of a state other than Texas, this Agreement will be governed by and construed in accordance with the laws of the State of Texas and the federal U.S. laws applicable therein, excluding any conflicts of law provisions, and the Customer and StataCorp agree to submit to the personal and exclusive jurisdiction of the courts located in Harris County, Texas.

The application of such different law shall be effective upon the receipt of such written notice by StataCorp. The parties agree that the United Nations Convention on Contracts for the International Sale of Goods will not apply to this Agreement. The failure of either party to require performance by the other party of any provision hereof shall not affect the full right to require such performance at any time thereafter, nor shall the waiver by either party of a breach of any provision hereof be taken or held to be a waiver of the provision itself. If any provision of this Agreement is found void and unenforceable, it will be replaced to the extent possible by StataCorp with a provision that comes closest to the meaning of the original provision. This Agreement and the documents referenced in this Agreement constitute the entire agreement between Customer and StataCorp relating to its subject matter and all terms herein and supersede all prior or contemporaneous agreements or understandings. This Agreement may be modified or changed only in writing signed by authorized representatives of Customer and StataCorp.

Considerato l’importante valore aggiunto, suggeriamo la sottoscrizione del Contratto di Manutenzione che, garantendo l’aggiornamento gratuito in caso di uscita di nuova release e il Supporto Tecnico della casa madre nonché della TStat sia on line sia tramite posta elettronica, consente all’utente di pianificare al meglio il proprio budget di spesa e di rimanere sempre aggiornato con la versione del Software.
Il Convegno rappresenta un importante punto di riferimento fra gli utenti di Stata e un’occasione unica di scambio interdisciplinare. Sono infatti graditi sia contributi metodologici, sia analisi applicate in diversi campi di ricerca, nuovi comandi scritti dagli utenti, nonché disparate applicazioni in Economia, Biostatistica, Scienze Sociali, Psicologia e gestione dei dati.
Le pubblicazioni della Stata Press sono potenti strumenti per l’apprendimento non solo di particolari metodologie statistiche ma anche di come utilizzare il Software Stata nel modo più efficiente. I testi illustrano passo per passo l’applicazione in Stata di metodi di analisi sviluppati in vari campi di ricerca e sono un importante supporto di approfondimento per tutti gli utenti.
Al contrario di un corso di formazione di tipo tradizionale, dove gli iscritti devono frequentare il corso di persona, i NetCourse della StataCorp si svolgono completamente on-line dove gli iscritti entrano a far parte di un circuito chiuso di posta elettronica. I NetCourse sono quindi più facilmente accessibili dal punto di vista logistico ed economico rispetto ai corsi di tipo tradizionale. Inoltre la struttura dei corsi è molto più flessibile, dato che non ci sono vincoli d’orario. Normalmente i corsi sono divisi fra alcune sessioni; all’inizio di ogni sessione, gli iscritti ricevono tutto il materiale rilevante: dispense; risposte alle domande e soluzioni dagli esercizi fatti nella sessione precedente. Fra le sessioni c’è un periodo di interruzione che permette agli iscritti di: ripassare le precedenti lezioni; fare alcuni esercizi relativi alla materia dell’ultima sessione; discutere problemi/idee con gli altri partecipanti e il responsabile del corso. Alla fine del corso, il circuito di posta elettronica rimane aperto per un periodo predefinito per permettere discussioni fra i partecipanti e il responsabile.
