Reziduálok

Reziduálok, in English residuals or remainders, is a term used in mathematics and statistics. In arithmetic, a reziduál is the integer that is left over when an integer is divided by another integer and the quotient is taken to be an integer. For example, when 10 is divided by 3, the quotient is 3 and the remainder is 1. This is often expressed using modular arithmetic notation, such as 10 mod 3 = 1.

In statistics, reziduálok refer to the differences between observed values and the values predicted by a statistical model. When a model is fitted to data, it attempts to capture the underlying patterns. The reziduál for a particular data point is the discrepancy between its actual value and the value estimated by the model. These reziduálok are crucial for evaluating the goodness-of-fit of a model and for identifying potential problems such as non-linear relationships or outliers. Analyzing the distribution and patterns of reziduálok can help statisticians refine their models or suggest alternative modeling approaches. They are a fundamental concept in regression analysis and time series analysis, among other statistical fields.
