必应词典为您提供Chi-square-measure的释义,网络释义: 卡方检验;卡方测度;卡方距离;
卡方距离(Chi-square Measure)由 χ 2 \chi^2 χ2统计量得到。统计学上的 χ 2 \chi^2 χ2统计量,最初由英国统计学家Karl Pearson在1900年首次提出的,因此也称之为Pearson χ 2 \chi^2 χ2统计量。 χ 2 \chi^2 χ2检验经常用来检验某一种观测分布是不是符合某一类典型的理论分布。观察频数与期望...

The conventional measuring mode ...
卡方检验是一种用途很广的计数资料的假设检验方法。它属于非参数检验的范畴,主要是比较两个及两个以上样本率( 构成比)以及两个分类变量的关联性分析。其根本思想就是在于比较理论频数和实际频数的吻合程度或拟合优度问题。 它在分类资料统计推断中的应用,包括:两个率或两个构成比比较的卡方检验;多个率或多个构成...

This chapter introduces students to nonparametric tests, which allow us to draw inferences about nominal or ordinal data. This chapter’s focus is the Chi-Square test, used for analyzing nominal-level data. The Goodness of Fit Χ2 tests an expectation of
Computing the Chi-Square Statistic After calculating the expected frequencies, we compute the chi-square statistic to measure how much the observed frequencies deviate from the expected frequencies under independence: \( \chi^2 = \sum \frac{(O_{ij} - E_{ij})^2}{E_{ij}} \) ...
Chi-square is a measure of association (i.e., nonrandomness), not agreement. An association might exist that is not a reflection of agreement. For example, two sets of ratings may be negatively associated; that is, the assignment of an event to one category by rater #1 may tend to co...
The chi-square calculator computes the χ2 parameters for an table of data. INSTRUCTIONS: Enter the following: (OB) Observed Values chi-square (χ2): The calculator returns: (DF) Degrees of Freedom (χ2) chi-square value (Σc) Column Sums (Σr) Row Sums (ΣOB) Total Sum How to ...
Summary: The chi-square divergence measure is extended to establish a measure of the information that a random sample gives about a Dirichlet process as a whole. After studying some of its properties, the expression obtained in sampling from step n to step $n+1$ is given, and its Bayesian...
