Relevant Parameters for β-Particle Tracks per Cell in Autoradiography Experiment Along with Quantities of Statistical Tests for Stirred and Unstirred Mixtures

Statistical test
Type and function <n>* σ ν χ̂2 R2
Stirred mixture
 Poisson 8.7 22 0.15
 LN 8.7 0.70 20 0.0071
 P-LN 8.7 0.80 20 0.0064
 LS fit to LN 12 ± 1.4 0.79 ± 0.075 20 0.0048 0.79

Unstirred mixture
 Poisson 7.8 21 0.99
 LN 7.8 0.67 20 0.0077
 P-LN 7.8 0.68 20 0.0046
 LS fit to LN 8.2 ± 0.37 0.57 ± 0.033 20 0.018 0.93
*

SEs are provided by LS fit of data to LN function using SigmaPlot.

Optimized value of σ is obtained via minimization of χ̂2 procedure.

The <n> and σ are obtained from raw data based on Lehman and Scavia (18) and minimization of χ̂2 value.
