Hi all, I am an incoming fresher in undergraduate pursuing economics as my majors. Have no prior knowledge of in-depth research but have read few literature reviews. Want to learn the basics of atleast one language in my first semester. Which language should I start from? R or Stata or Python

I’m planning to play slots on an upcoming cruise expecting to lose money but also to get free cruise offers.

I’m planning to have $2500 cash with me and to do 750 $10 spins. I don’t know exact payback percentages but assuming an 80% payback rate how much would I lose on average with the 750 $10 spins. Also, what is the risk of ruin before reaching 750 spins? Thanks.

Hi! I am working on a meta-analysis of ten studies (I'm permitted to get advice about the stats elements!), and am getting confused around the heterogeneity statistics. My I2 is around 85%, and Cochran's Q = 44 (p= 0.00). However, my tau2 is low at 0.10.

It seems that in most papers I've read, a high I2 is accompanied by a high tau2. I assume that for mine, this means that while a high proportion of the variation is due to heterogeneity, the absolute magnitude of the variation is low. This makes sense in theory, but the point estimates of each study do vary quite a lot.

If anybody knows how this might be interpreted, I would really appreciate any advice :)

In my small simulation, requiring an independent verification PASS reduced false approvals, but one fraud still passed the independent check.

How should I represent imperfect verification reliability without pretending my score is calibrated?

Hello, I have a fractional design (2^4-1) with variables A, B, C, ABC and response R, but I am unsure how to include the measurement repeatability of the response when analysing the results.

For example, I know my response variable measurement has a repeatability of 0.234 (3-sigma value), and from my DOE analysis I got that the absolute effect of variable A on the response variable is 0.1.

As the effect of A is less than my repeatability does that mean I cannot really conclude anything about the impact of A on R?

Thanks for your help
