1. Low variability on your X means that you'll have less precision in your estimates, but that doesn't seem to be a problem as your coefficient's variations are already low. For more information, look into this CrossValidated post.

2. It's very hard that you don't have an omitted variable that affects you Y, given the very complex nature of what determines GDP, and how hard is to condense all the political and economic characteristics into two indexes. As this indexes have a lot of things inside them, it's also hard to interpret them (the "effect of a gain of 1 on the idex of political transformation on the GDP" isn't much clear). Having said this, if you're not too much concerned with this fact, and you think that the indexes are well made, then they should capture the affects that the economics and politics characteristics have on the GDP. There can be other dimensions that you could want to look into, such as institutions.

3. From the plot, they wouldn't be different if one of the lines were contained in the other's confidence interval (grey area), which is not true. In the summary, you can see that both the coefficient associated with the interaction (slope of the lines) and with the dummy (intercept of the lines) are significantly different than 0.

Well, it seens that the array type values changed on the textField onChange.

Even the text input type was a number, it changes to string if i put it on the onChange method, i was not paying attetion to that (i am new to dart).

The items in the list was always creating with int values, but it changed to string in the middle of the process...

Try this

You can basicaly redefine and reorder every grid element in a mediaquery after it. Just adjust the values to your liking

predictInterval is in the merTools package (it's worth specifying this when you're asking about functions that are not in the base/recommended packages). (glmer is in lme4, which is also extra, but is more widely used/better known.)

?predictInterval says:

By drawing a sampling distribution for the random and the fixed effects and then estimating the fitted value across that distribution, it is possible to generate a prediction interval for fitted values that includes all variation in the model except for variation in the covariance parameters, theta.

Thus

• "fixed" means to incorporate only the uncertainty in the fixed-effect parameters;
• "random" means to incorporate only the uncertainty due to the variation of random-effect groups around the population mean
• "full" combines these two sources of uncertainty
• "all" returns a data frame with all three of these values, with an additional column effect that can be "combined" (="full"), equal to any of the random-effects grouping variables (i.e. separating components due to different grouping variables in a model with more than one), or "fixed"

If include.resid.var is TRUE then the residual variance is also included in the uncertainty.

It doesn't make any sense at all. If you look at your levels now:

Apparently the maximum length of a single line is 512 characters, and the line 144 has 579 characters

If both tables share a common parent you can use table:nth-child(2) or simply add a class to your second table and use table.myTableClass tr:nth-child(odd) etc..

You might consider using :nth-of-type for your color striping, btw, it's a little cleaner/simpler. CSS Tricks

Here is a jsfiddle where I used the code from your updated question to get the two tables to use different colors. https://jsfiddle.net/wq6fc8p2/

I'd suggest you use defaultdict to get ur data into a dictionary, and read directly into a dataframe; it also removes the need to create an empty dataframe to fill:
