| 21. | That fact, and the normal and chi-squared distributions given above, form the basis of calculations involving the quotient
|
| 22. | This has approximately a chi-squared distribution with " k " & minus; 1 degrees of freedom.
|
| 23. | Kleinberg has shown that the optimal clustering coefficient for this model is q = 2, or an inverse square distribution.
|
| 24. | The primary reason that the chi-squared distribution is used extensively in hypothesis testing is its relationship to the normal distribution.
|
| 25. | The atlas was the first to present grid-square distribution maps for all breeding birds at a Europe-wide level.
|
| 26. | One might hope that the resulting test statistic would have approximately a chi-square distribution when the null hypothesis is true.
|
| 27. | Has a chi-squared distribution with \ nu = n-1 degrees of freedom ( by Cochran's theorem ).
|
| 28. | Pearson showed that the chi-squared distribution, the sum of multiple normal distributions, was such an approximation to the multinomial distribution
|
| 29. | Other examples of unimodal distributions include Cauchy distribution, Student's t-distribution, chi-squared distribution and exponential distribution.
|
| 30. | Specifically, the scaled inverse chi-squared distribution can be used as a conjugate prior for the variance parameter of a normal distribution.
