Hi guys!

Which function is used to format a numerical value as a positive real number?

Thanks!

There is the format() function that returns a formatted character version of a number.

What do you need to accomplish?

The formatting of the numbers is not the problem here. Number formatting is only relevant for the display of results, not for the calculation.

I will first note that the negative value of your intercept is -2.07 and has a standard error of 1.47, giving a p value of 0.16. That means that the intercept is not convincingly different from zero (unless you have set a very, very weak threshold on p for rejecting the null hypothesis). A common expression of that would be that the intercept's difference from zero is not *statistically significant* but that use of *significant* leads to a lot of misunderstanding. If you have a strong reason to believe that the intercept cannot be negative, these results are consistent with that.

Your desire to force Y to be positive real numbers does not seem helpful. You can check that they are positive or non-negative with

```
all(Y > 0)
#or
all(Y >= 0)
```

Having positive Y values in no way guarantees that the intercept will be positive. If that does not make sense to you, I can explain it further.

I want to accomplish an OLR regression with Y <- funding amount.

Funding amount is currently formatted as.numeric. But I receive a negative estimate for the b0 of the regression, which should not be the case:

Coefficients:

Estimate Std. Error. t value Pr(>|t|)

(Intercept) -2.065402 1.472629. -1.403 0.16154

So, I want to format Y to be a positive real number. Hope this would improve the outcome of my regression.
