Hi @aboks, Thank you for your continued interest in improving MathPHP. At some point in the past I remember `number` being a valid PHPDoc pseudo type, but I can't seem...
Hi @mcatal, Thank you for your interest in MathPHP. Can you provide a more thorough explanation of what kind of functionality you are requesting? Also, can you link to some...
Hi @zjsxwc, Thanks for your interest in MathPHP. I'm not familiar with KPHP. What doesn't work with it, and what changes, if any, would be required to support it? Thanks,...
Hi, Thanks for your interest in MathPHP. Let's see if we can figure out what is going on. Can you provide the values for `$points` and `$x` here that are...
This unit test will reproduce the issue. ```php public function testBugIssue429() { // Given $points = [[5,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,0],[8,1],[8,0],[8,1],[8,1],[8,1],[8,1],[8,0],[8,1],[8,0],[8,1],[8,0],[8,1],[8,0],[8,1],[8,0],[8,1],[8,1],[8,1],[8,0],[8,1],[8,0],[8,1],[8,1],[8,1],[8,0],[8,1],[8,0],[8,1],[8,0],[8,1],[8,0],[8,1],[8,0],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1],[8,1]]; $x = 5.0; // And $regression = new Linear($points); // When $ci =...
The issue looks like it is in the StudentT distribution's PDF. This unit test using the data from this bug currently fails, producing 0 instead of the expected result. ```php...
I added additional test cases in the develop branch for the StudentT `pdf` up until the point where the tests still pass. The library works fine up until a `v`...
Looks like I didn't push the new test cases. Here they are for reference. ```php /** * @return array [t, ν, pdf] * Generated with R dt(t, ν) from package...
@Beakerboy, Thanks for providing a fix so quickly. The StudentT PDF is now always producing answers for any input, which is a great improvement. I have a question, in @drjayvee's...
@drjayvee, This has been fixed in [Version 2.5.0](https://github.com/markrogoyski/math-php/releases/tag/v2.5.0). You should not get any more division by zero errors. Many thanks to @Beakerboy for numerous improvements in the special functions that...
