Label	Id	Description
median centering	OBI_0200030	[A median centering is a data transformation that takes as input an n-dimensional (real) vector, performs a median calculation on its components, and subtracts the resulting median from each component of the input.]
leave one out cross validation method	OBI_0200033	[is a data transformation : leave-one-out cross-validation (LOOCV) involves using a single observation from the original sample as the validation data, and the remaining observations as the training data. This is repeated such that each observation in the sample is used once as the validation data]
statistical model validation	OBI_0000792	[A data transformation which assesses how the results of a statistical analysis will generalize to an independent data set.]
cross validation objective	OBI_0200188	[A cross validation objective is a data transformation objective in which the aim is to partition a sample of data into subsets such that the analysis is initially performed on a single subset, while the other subset(s) are retained for subsequent use in confirming and validating the initial analysis.]
K-fold cross validation method	OBI_0200032	[K-fold cross-validation randomly partitions the original sample into K subsamples. Of the K subsamples, a single subsample is retained as the validation data for testing the model, and the remaining K - 1 subsamples are used as training data. The cross-validation process is then repeated K times (the folds), with each of the K subsamples used exactly once as the validation data. The K results from the folds then can be averaged (or otherwise combined) to produce a single estimation. The advantage of this method over repeated random sub-sampling is that all observations are used for both training and validation, and each observation is used for validation exactly once. 10-fold cross-validation is commonly used]
time sampled measurement data set	IAO_0000584	[A data set that is an aggregate of data recording some measurement at a number of time points. The time series data set is an ordered list of pairs of time measurement data and the corresponding measurement data acquired at that time.]
time stamped measurement datum	IAO_0000582
boostrapping	OBI_0200035	[Bootstrapping is a statistical method for estimating the sampling distribution of a statistic by sampling with replacement from the original data, most often with the purpose of deriving robust estimates of standard errors and confidence intervals of a population parameter like a mean, median, proportion, odds ratio, correlation coefficient or regression coefficient]
jackknifing method	OBI_0200034	[Jacknifing is a re-sampling data transformation process used to estimate the precision of sampling statistics and is a resampling method]
pareto scaling	OBI_0200037	[A pareto scaling is a data transformation that divides all measurements of a variable by the square root of the standard deviation of that variable.]
Benjamini and Hochberg false discovery rate correction method	OBI_0200036	[A data transformation process in which the Benjamini and Hochberg method sequential p-value procedure is applied with the aim of correcting false discovery rate]
looking up a centrally registered identifier	IAO_0000580	[A planned process in which a request to a CRID registry is made to return the information associated with a CRID symbol]
centrally registered identifier registry	IAO_0000579	[A CRID registry is a dataset of CRID records, each consisting of a CRID symbol and additional information which was recorded in the dataset through a assigning a centrally registered identifier process.]
RNASE V1 structure mapping assay	OBI_0001012	[A single-nucleotide-resolution ribonucleic acid structure mapping assay that determines nucleic acid secondary structure at a nucleotide resolution scale using RNAse V1 as reagent and enzymatic probe]
secondary structure of RNA molecule	OBI_0000896	[]
ENU structure mapping assay	OBI_0001011	[A single-nucleotide-resolution nucleic acid structure mapping assay that determines the secondary structure of a nucleic acid at the nucleotide resolution scale which uses ENU as reagent and chemical probe]
RNA ADA I RNA structure mapping assay	OBI_0001019	[A single-nucleotide-resolution ribonucleic acid structure mapping assay that determines nucleic acid secondary structure at a nucleotide resolution scale using RNA adenosine deaminase I as reagent and enzymatic probe.]
Rhodium DNA structure mapping assay	OBI_0001018	[A single-nucleotide-resolution nucleic acid structure mapping assay that determines nucleic acid secondary structure at a nucleotide resolution scale using Rhodium as reagent and chemical probe.]
single-nucleotide-resolution nucleic acid structure mapping assay	OBI_0000870	[An assay that provides information about the secondary structure of nucleic acids using chemical or enzymatic probing to establish the extent of base-pairing or solvent accessiblity.]
DNASE 1 structure mapping assay	OBI_0001016	[A single-nucleotide-resolution deoxyribonucleic acid structure mapping assay which uses DNAse 1 as reagent and enzymatic probe to generate data and information at nucleotide resolution scale contributing to the determination of nucleic acid secondary structure]
