The assumptions involved in using risk difference and odds ratio scales for calculating NNTs are discussed.
The sample size was determined using power calculations in order to ensure at least 90% power to detect a magnitude of association at the odds ratio scale of 1.5 at 5% statistical significance for an exposure that occurs among 10% of the controls.
But incommensurability on a ratio scale does not imply incommensurability on every scale an ordinal scale, for instance.
A difference scale (for example risk difference), as opposed to a ratio scale, was chosen only infrequently.
Finally, this tutorial discusses methods for running analyses on the log hazard ratio scale.
DCSTREAM runtime is a ratio scale variable which is a positive measurement on a non-linear scale, approximately at exponential scale for the entire length of stream.
Ratio scales with a natural unit, such as those used for counting discrete objects and for representing probabilities, were named "absolute" scales.
We present methods for meta-analysing different statistics summarising survival data on the hazard ratio scale.
Image feature detection, aspect ratio, scale, crop.
For all scale items, behavioral and attitudinal, a Likert scale was used where the middle points were not defined, allowing the scale to be a true ratio scale.
