Intelligence Tests: Their Significance for School and Society

The Qualitative Tests for Acetone Bodies ; Their Significance and Value

The qualitative tests most commonly used for acetone bodies in the urine are the sodium nitroprusside test and the ferric chloride test. These are usually regarded as selective tests for acetone and diacetic acids, respectively. In fact, few text-books on methods of analysis mention the sodium nitroprusside test as a test for diacetic acid, while some workers-Harding and Ruttan (1) and Hunter (...

Significance Tests for Periodogram Peaks

We discuss methods currently in use for determining the significance of peaks in the periodograms of time series. We discuss some general methods for constructing significance tests, false alarm probability functions, and the role played in these by independent random variables and by empirical and theoretical cumulative distribution functions. We also discuss the concept of “independent freque...
