Chi-square Distribution: One of the characteristics of a chi-square distribution is that is positively skewed. Chi-square is used to test the overall significance of a regression model. Answer and Explanation:

plotChiSquaredFit(test) plots the empirical CDF of the chi-squared probabilities of the ratio between the observed and the estimated variance stratified by count levels into five equal-sized bins. Use this plot to assess the goodness-of-fit. test, an output of the nbintest function, is a ...
The Sum of the squares of the k-independent standard random variables is called the Chi-Squared distribution. Pearson’s Chi-Square Test formula is - Where X^2 is the Chi-Square test symbol Σ is the summation of observations O is the observed results E is the expected results The ...
