    This study introduces a new algorithm for designing limiting dilution analysis experiments and evaluates statistical methods for estimating cell frequency. The jackknife maximum likelihood method is recommended for accurate cell frequency determination.

    Area of Science:

    • Biostatistics
    • Cell Biology
    • Experimental Design

    Background:

    • Limiting dilution analysis is crucial for estimating cell frequencies.
    • Optimizing experimental design and statistical methods are key challenges.

    Purpose of the Study:

    • To develop a mathematical algorithm for experimental design in limiting dilution analysis.
    • To evaluate and recommend the most effective statistical method for frequency estimation.

    Main Methods:

    • A mathematical algorithm was developed to determine optimal replicate culture groups and cell numbers per well.
    • Monte Carlo experiments were conducted to compare minimum chi-square, maximum likelihood, and jackknife maximum likelihood methods.

    Main Results:

  • The developed algorithm provides useful data when a priori estimates are accurate and cells are viable.
  • All evaluated statistical methods proved useful for data analysis.
  • The jackknife maximum likelihood method demonstrated superior performance in simulations.

    • Conclusions:

    • The jackknife maximum likelihood estimation procedure is proposed as the optimal method for limiting dilution analysis.
    • The maximum likelihood method is a viable alternative, performing as the second-best option.
