Hello, so there seems to be common knowledge for people to use dummy variables while using (ordinal) logistic regression but using jamovi I must've totally missed that due to the videos I have been watching haven't demonstrated that despite several different categories within their variables. Kindly look at the video evidence below if you would like. I was wondering if anyone who is familiarized with jamovi could tell me whether I need to make these dummy variables or not? Thanks https://www.youtube.com/watch?v=QnG8Tq80Qwc&t=55s https://www.youtube.com/watch?v=nuyEUEBf-GQ https://www.yout ..read more

Hi all, I’ve stumbled upon this problem while looking at subgroups (e.g. men and women) of clinical trials, but I can’t find a general solution. Suppose you have a quantity of interest, (e.g., mean or a difference thereof), and you have two disjunct subsamples n1, n2 that make up your sample of size N. Let p = n1/N be the proportion of the first sample w.r.t. the whole sample and x be your estimator of interest. Then the estimator of the whole sample is p(x1) + (1-p)x2 = x Where x1, x2 are the estimated on their respective subsamples. I verified that this is true for the sample mean, variance ..read more

I’m going to be starting my Masters Thesis in my stats program. I have narrowed down two projects with different faculty members. One of them is entirely self guided, and that advisor doesn’t really have any expertise in this area and the other one is basically with another faculty member but the research topic is within his domain, so he can help me, but the application strays too far from what industry I want to be in. Project 1: Causal Machine Learning, and nonparametric estimation for identifying heterogenous treatment effects in advertising/marketing data. There’s a dataset by a company ..read more

Hello. I’m struggling with how I structure my results section. I have a histogram and a box plot both showing the same data. The box plot shows outliers the histogram does not. For context I am using Jamovi. I have descriptives, including a Shapiro wilks test. One of the results on this test is P=0.021 which I assume means abnormal distribution? I ran a One way Between subjects ANOVA. A Levene’ variance check and a Simple Contrast using Tukey as my Post Hoc test. My questions are: 1.Do I need to include both the Histogram and box plots figures? If not which do I choose? Which tables (descrip ..read more
