Let X follow a gamma distribution with θ = 2 and α = r 2, where r is a positive integer. Then the probability density function of X is: f ( x) = 1 Γ ( r / 2) 2 r / 2 x r / 2 − 1 e − x / 2. for x > 0. We say that X follows a chi-square distribution with r degrees of freedom, denoted χ 2 ...

Calculate chi-square statistics in R - Stack Overflow
WebMar 28, 2024 · Hence, if the Chi-Square test statistic comes out to be greater than 18.475 then the results of the test would be considered statistically significant. Relation of alpha and chi-square statistic. Alpha and chi-square critical values are inversely proportional to each other. In other words, larger critical values lead to smaller alpha values. WebMar 18, 2024 · R provides us the pchisq() function using which we can find the p-value of a Chi-Square Statistic. The syntax of this function is given below: Syntax: pchisq(q = “value”, df = “value”, lower.tail = TRUE) ... The probability in the right of q in the Chi-Square distribution is returned. Note that by default lower.tail is TRUE. WebChi-Square Distribution in R; by Michael Foley; Last updated about 4 years ago; Hide Comments (–) Share Hide Toolbars saint john\\u0027s high school
