SciPy - Statistical Functions (scipy.stats) Basics
Which function from scipy.stats would you use to get the probability density function (PDF) value for a normal distribution at x=0?
Anorm.cdf(0)
Bnorm.pmf(0)
Cnorm.pdf(0)
Dnorm.sf(0)
Step-by-Step Solution
Solution:

  1. Step 1: Identify the function for PDF in scipy.stats

    For continuous distributions like normal, PDF is accessed by .pdf()

  2. Step 2: Differentiate from other functions

    cdf() is cumulative, pmf() is for discrete distributions, sf() is survival function.

  3. Final Answer:

    norm.pdf(0) -> Option C

  4. Quick Check:

    PDF function = .pdf() [OK]
Quick Trick: Use .pdf() for continuous PDF values [OK]
Common Mistakes:
MISTAKES
  • Using cdf() instead of pdf()
  • Using pmf() for continuous distributions
  • Confusing survival function sf() with PDF
