2. Bootstrapping (statistics) - Wikipedia

   en.wikipedia.org/wiki/Bootstrapping_(statistics)

   Bootstrapping estimates the properties of an estimand (such as its variance) by measuring those properties when sampling from an approximating distribution. One standard choice for an approximating distribution is the empirical distribution function of the observed data.

3. M-estimator - Wikipedia

   en.wikipedia.org/wiki/M-estimator

   M-estimator. In statistics, M-estimators are a broad class of extremum estimators for which the objective function is a sample average. [ 1] Both non-linear least squares and maximum likelihood estimation are special cases of M-estimators. The definition of M-estimators was motivated by robust statistics, which contributed new types of M ...

4. Construction estimating software - Wikipedia

   en.wikipedia.org/wiki/Construction_estimating...

   Construction estimating software. Construction cost estimating software is computer software designed for contractors to estimate construction costs for a specific project. A cost estimator will typically use estimating software to estimate their bid price for a project, which will ultimately become part of a resulting construction contract.

5. Bootstrapping (finance) - Wikipedia

   en.wikipedia.org/wiki/Bootstrapping_(finance)

   Bootstrapping (finance) In finance, bootstrapping is a method for constructing a ( zero-coupon) fixed-income yield curve from the prices of a set of coupon-bearing products, e.g. bonds and swaps. [ 1 ]

6. Statistical hypothesis test - Wikipedia

   en.wikipedia.org/wiki/Statistical_hypothesis_test

   A statistical hypothesis test is a method of statistical inference used to decide whether the data sufficiently support a particular hypothesis. A statistical hypothesis test typically involves a calculation of a test statistic. Then a decision is made, either by comparing the test statistic to a critical value or equivalently by evaluating a p ...

7. Estimation of covariance matrices - Wikipedia

   en.wikipedia.org/wiki/Estimation_of_covariance...

   The sample covariance matrix (SCM) is an unbiased and efficient estimator of the covariance matrix if the space of covariance matrices is viewed as an extrinsic convex cone in Rp×p; however, measured using the intrinsic geometry of positive-definite matrices, the SCM is a biased and inefficient estimator. [ 1]
