In statistics, maximum likelihood estimation (MLE) is a method of estimating the parameters of an assumed probability distribution, given some observed data.This is achieved by maximizing a likelihood function so that, under the assumed statistical model, the observed data is most probable. Cross-validation, sometimes called rotation estimation or out-of-sample testing, is any of various similar model validation techniques for assessing how the results of a statistical analysis will generalize to an independent data set. That is, it concerns two-dimensional sample points with one independent variable and one dependent variable (conventionally, the x and y coordinates in a Cartesian coordinate system) and finds a linear function (a non-vertical straight line) that, as accurately as possible, predicts For example, pharmaceutical companies have been known to hide negative studies and researchers may have overlooked unpublished An estimator or decision rule with zero bias is called unbiased.In statistics, "bias" is an objective property of an estimator.

Economics (/ k n m k s, i k -/) is the social science that studies the production, distribution, and consumption of goods and services..

Purchasing power parity (PPP) is the measurement of prices in different countries that uses the prices of specific goods to compare the absolute purchasing power of the countries' currencies, and, to some extent, their people's living standards.In many cases, PPP produces an inflation rate equal to the price of the basket of goods at one location divided by the price of the basket of when inflation declines to a lower rate but is still positive.
