| Popis: | Standard deviations of yarn break data, taken by uniform increments of spindle hours, increased linearly with average rate of breakage and were larger than expected for a Poisson distribution. Transforming the numbers of breaks to log10 (1 + number of breaks) stabilized the variance. In a specific case, analysis of data for 720 spindle hours per yarn taken by 12 increments of 60 hours yielded 95% confidence limits describing the average number of breaks per yarn as within 30% of the observed number of breaks. |
