Solidity provides value types and reference types. Reference types are arrays, mappings and structs. Value types are all other data types like string, int, and boolean. When you define a reference type you have to define the "data location" to determine where the data is stored. The three data locations are memory, storage and calldata. In this ...

The Bland-Altman plot, or difference plot, is a graphical method to compare two measurements techniques (Bland & Altman, 1986 and 1999). In this graphical method the differences (or alternatively the ratios) between the two techniques are plotted against the averages of the two techniques. ... How to define the Maximum allowed difference ...

To illustrate how a Bland-Altman plot shows these types of data anomaly, let us examine five possible pairings in 20 subjects of balance with and without combat arms ear plugs (CAEPs). 7 It is asked if CAEPs affect the balance of subjects performing balance-affected tasks, such as piloting an aircraft, making terrain judgments, or making analog mechanical or computer …

The hard choices -- what we most fear doing, asking, saying -- are very often exactly what we need to do. How can we overcome self-paralysis and take action? Tim Ferriss encourages us to fully envision and write down our fears in detail, in a simple but powerful exercise he calls "fear-setting." Learn more about how this practice can help you thrive in high-stress environments …

The Bland-Altman (mean-difference or limits of agreement) plot and analysis is used to compare two measurements of the same variable. That is, it is a method comparison technique. For example, an expensive measurement system might be compared with a less expensive one or an intrusive measurement system might be

Oct 15, 1994 · When presenting or analysing measurements of a continuous variable it is sometimes helpful to group subjects into several equal groups. For example, to create four equal groups we need the values that split the data such that 25% of the observations are in each group. The cut off points are called quartiles, and there are three of them (the middle one also being …
