מודלים ואלגוריתמים: מה ההבדל ומה הבעיה

לאחרונה השתתפתי בכמה דיונים בפייסבוק שהגיעו למבוי סתום. ניסיתי להבין למה זה קורה ולבסוף הבנתי: אני דיברתי על מודלים והם דיברו על אלגוריתמים. לכאורה לא צריכה להיות שום בעיה. מודל זה דבר אחד, אלגוריתם זה דבר אחר. אם תחפשו בגוגל מודל, לא תמצאו שום מקום שיטען כי מודל הוא אלגוריתם. גם ההיפך נכון. אז מה […] Read More

3 problems with mean imputation

In a previous article, I showed how to use SAS to perform mean imputation. However, there are three problems with using mean-imputed variables in statistical analyses: Mean imputation reduces the variance of the imputed variables. Mean imputation shrinks standard errors, which invalidates most hypothesis tests and the calculation of confidence [...]

Teaching statistics tip: Know your students
