filtrare Explanation: proceduri de filtrare (a datelor) Nu am întâlnit termenul în domeniul statisticii medicale, dar prin analogie cu jurnalismul (gatekeeping = filtrarea informaţiilor) aş traduce în acest mod. HTH |

| Reference: Referinte "gatekeeping" Reference information: Am incercat sa gasesc ceva mai la obiect, obiectul fiind in cazul de fata statistica. Iata ceva citate si linkuri: http://www3.interscience.wiley.com/journal/119142328/abstrac... http://biopharmnet.com/doc/ntgp2008.pdf “Tree-structured gatekeeping tests in clinical trials with hierarchically ordered multiple objectives.” “The proposed approach is based on the principle of closed testing and generalizes the serial and parallel gatekeeping approaches developed by Westfall and Krishen” http://www.ncbi.nlm.nih.gov/pubmed/17054103 “include gatekeeping procedures, which are often applied in clinical trials when primary and secondary objectives are investigated, and multiple test procedures based on hypotheses which are completely ordered by importance” http://www3.interscience.wiley.com/journal/114176382/abstrac... “gatekeeping property (the monotonicity condition was introduced by Hommel, Bretz and Maurer [2] to obtain shortcuts to Bonferroni-based closed procedures). A modification of the algorithm is shown to rectify this problem.” “Gatekeeping property. A hypothesis Hij in Fi, i = 2, . . . ,m, cannot be rejected (i.e., is automatically accepted) if at least one hypothesis in its serial rejection set (denoted by RS ij) is accepted or all hypotheses in its parallel rejection set (denoted by RP ij) are accepted. Here RS ij and RPij consist of relevant hypotheses (determined by logical relations) from families Fk for k < i.” http://biopharmnet.com/doc/ntgp2008.pdf “Bonferroni - (numit şi testul Dunn) implică o succesiune de teste t la care pragul de semnificaţie este divizat prin numărul de comparaţii. De exemplu, pentru a păstra nivelul de semnificaţie global la 0,05 în m comparaţii, fiecare test t de comparare este efectuat la pragul de 0,05/m. Rezultă că procedura poate fi aplicată doar atunci când există puţine comparaţii, în caz contrar este greu de găsit o diferenţă semnificativă (şi creşte riscul unei erori de speţa II).” http://profs.info.uaic.ro/~val/statistica/StatWork_5.pdf “Folosind ca si test statistic analiza variatiei ANOVA si testul post hoc cu comparatii multiple Bonferroni s-a evidentiat diferente semnificative ale amplitudinii potentialului nervilor tibiali intre lotul A si respective loturile B si C. Nu s-au evidentiat diferente semnificative ale timpului de latentă intre cele trei loturi.” http://www.umfcluj.ro/Document_Files/Doctorat-Rezumate-Teze-... http://www.psihologiaonline.ro/download/art/A015_Copilulsimp... Testul post-hoc valoare ajustata cu comparatii multiple Bonferoni “Un arbore de decizie (Decision Tree) este un model de clasificare sau estimare care poate fi privit ca un arbore. Fiecare subarbore din componenta sa reprezintă un răspuns la o întrebare de clasificare, frunzele arborelui sunt partitii sau segmentări ale setului de date în functie de clasificarea realizată, iar nodurile prezintă informatii statistice.” http://steconomice.uoradea.ro/anale/volume/2006/statistica-s... |
