Re: Binomial distribution (distrACTION)
Hello, Thank you very much for this detailed answer. Always assume that X is a binomial law of parameters n = 12 and p = 0.3. With WolframAlpha, for example, it is possible to calculate P(4.5 ≤ X ≤ 6.5). The result gives 0.2377 (P(X = 5) + P(X = 6) = 0.1585 + 0.0792). In Jamovi, currently, the resul...

Re: Binomial distribution (distrACTION)
Hello, Another small remark concerning the example that MAgojam proposes. We see that according to Jamovi P(X ≥ 6.5) = 0.118. What we also see on the figure, is that P(X ≥ 6.5) = P(X=7) + P(X=8) + ... + P(X=12) (the probability sought is represented by orange bars). According to R, > sum(dbinom(7:12...

Re: Binomial distribution (distrACTION)
Hello, In my opinion, this is a bug. Even if the modalities of a binomial variable are discrete, it should be possible to correctly calculate the value of the distribution function for any real number. Here's how the bug could be fixed. I will try to make a proposal in github, but here is already th...

Binomial distribution (distrACTION)
Hello, DistrACTION sometimes provides an incorrect answer. Here is an example. Suppose that X is a random variable following a binomial law of parameters n = 12 and p = 0.3. Calculate P(X >= 6.5). According to Jamovi, P(X >= 6.5) = 0.118 (see DistrACTION_example_01.png), while P(X >= 7) = 0.039 (see...

import file containing numbers with four decimal places
Hello,
When I try to import into Jamovi (1.2.27) a csv file containing numbers with four decimal places, these numbers are always rounded to three decimal places. How to get around this difficulty?
Thank you in advance for your answer.
Best regards

Option 'jmv' -> 'bruce' ?
Hello,
Thank you very much for putting a new solid version at our disposal. In the analysis menu appears a new option 'jmv' offering only one choice 'bruce' (a part of log-linear analysis). Is not it a small bug?
Thank you very much, best regards

Expected counts in a chi-square goodness of fit test
Hello,
In a chi-square goodness of fit test (N outcomes), I wonder if it would be possible to choose the format of the expected counts. Currently these are rounded to the unit and sometimes one needs a greater precision.
Thank you for your excellent work!

Levene's test of equality of variances
Hello, Jamovi is a very intuitive software. Thank you so much. It allows, among other things, to test the equality of the variances using the Levene's test (independent samples T Test). The statistic of this test is a Fisher's F and I propose that you add in the output the second degrees of freedom ...
