Each fixed telemetry station consisted of an 8-m high metal tower supporting two parallel 6-element Yagi antennas, connected to a precision null combiner (Tac-5, Telonics, Mesa, AZ, USA) and to a telemetry receiver TRX-1000SS, Wildlife Materials, Carbondale, IL, USA).
The null precision is (T P + F N) / E.
Although Indigenous men had the lowest rates of first and re-diagnoses, it was only in the combined analysis that the difference had adequate precision to reject the null hypothesis (adjusted RR = 0.25, 95 % CI 0.06, 0.97).
The choice of analyzing the sign of the fold changes in a pool of genes, rather than the variance of a single gene, may lead to a loss of statistical information, to the advantage of greater precision in discarding the null hypothesis.
When we averaged the THM concentration across the calendar years 1995 2001, in place of the five-year lag, and re-fitted the Bayesian model, the positive associations became slightly stronger and the negative associations shifted towards the null with reduced precision.
The 95% CI was the estimate's precision, and if it excluded the null value of zero, the difference between groups was judged to be statistically significant.
a Because of finite numerical precision, for our putposes a flux is null when it is smaller than 10-6.
This adjustment maintains the null distribution at a constant precision, which accounts for the constant rate of false positive (or type I error) and hence nearly constant nPPV.
Non-differential random errors typically deflate risk estimates for dichotomous and continuous exposures (and trend effects for ordered polytomous exposures) towards the null (no effect), reduce their precision, and may therefore mask true effects.
We then used a bisection method to estimate to a 10-2 precision the value that renders the overall charge null.
It is therefore of interest to motivate researchers to control the type II error, or to think a priori about the precision they want to have, before testing the null hypothesis regarding the structure of a scale.
