Parameters of distribution
Curve Fitting Methods
Mind effective number of data
Confidence limits for frequency distribution
FX(x) = 1 - 1/T
pj = 1/k = F(zj) - F(zj-1)
e.g. for 5 classes this is p = 0.20, 0.40, 0.60, 0.80 and 1.00
Chi-squared goodness of fit test
877 = 877
877 + 0.674x357 = 1118
From the table it follows for the test statistic:
At significance level = 5%, according to Chi-squared distribution for = 4-1-2 df the critical value is at 3.84, hence c2 < critical value, so H0 is not rejected
