I’m using parametric models to calculate some reliability items.
The question is how to perform the adhesion tests (Test Kolmogorov-Smirnov- KS and the Square chi - χ2) .
I tried using the "Ks.test" function
(ex: Ks.test(file$time,"pweibull", Shape= range,Scale= alfa_wei))
and
"chisq.test" (eg chisq.test(rlnorm(n,Mean = Y, sd = Sy)).
Meanwhile the p-valor
is not correct, but in the test ks
the statistic is correct (D). How to perform these tests in R for reliability data?
Data used were:
Tempo tipo
794 1
676 1
573 1
484 1
406 1
339 1
282 1
233 1
191 1
156 1
126 1
102 1
81 1
64 1
Results R:
range = 1.476715 alfa_wei= 357.5189
One-sample Kolmogorov-Smirnov test
date: file$Time D = 0.10253, p-value = 0.995 Alternative hypothesis: two-Sided
The correct p-value result should be: D = 0,1006, p-value = 0,386
For the chi square test I did not succeed.
How do I do these tests in R for reliability data?
