Scott's rule is a method to select the number of bins in a histogram. [1] Scott's rule is widely employed in data analysis software including R , [ 2 ] Python [ 3 ] and Microsoft Excel where it is the default bin selection method.
High-multiplicity bin packing is a special case of the bin packing problem, in which the number of different item-sizes is small, while the number of items with each size is large. While the general bin-packing problem is NP-hard , the high-multiplicity setting can be solved in polynomial time, assuming that the number of different sizes is a ...
Payment card numbers are composed of 8 to 19 digits, [1] The leading six or eight digits are the issuer identification number (IIN) sometimes referred to as the bank identification number (BIN). [2]: 33 [3] The remaining numbers, except the last digit, are the individual account identification number. The last digit is the Luhn check digit.
Sturges's rule [1] is a method to choose the number of bins for a histogram.Given observations, Sturges's rule suggests using ^ = + bins in the histogram. This rule is widely employed in data analysis software including Python [2] and R, where it is the default bin selection method.
When the 2321 data cell was discontinued in January 1975, [5] the addressing scheme and the device itself was referred to as CHR or CTR for cylinder-track-record, as the bin number was always 0. IBM refers to the data records programmers work with as logical records , and the format on DASD [ a ] as blocks or physical records .

Andromeda is a peptide search engine based on probabilistic scoring, developed by Jürgen Cox and others at the Max Planck Institute of Biochemistry. It can handle data with arbitrarily high fragment mass accuracy and is able to assign and score complex patterns of post-translational modifications, such as highly phosphorylated peptides. It can ...
If a spectrum of an unknown chemical compound is available, a reverse search can be carried out by entering the values of the chemical shift, frequency or mass of the peaks in the NMR, FT-IR or EI-MS spectrum respectively. This type of search affords all the chemical compounds in the database that have the entered spectral characteristics. [6]
