dataset 1 required

Accepts a dataset with the following format: []number.

Outputs the Pearson correlation coefficient between dataset_1 and dataset_2 (1 = perfect positive linear correlation, -1 = perfect negative). Items coerce per number rules (numeric strings and booleans count, other values are dropped) and both datasets are truncated to the shorter filtered length before pairing. Outputs 0 when either dataset ends up empty or has zero variance. Example: [1,2,3] vs [2,4,6] -> 1.

A typical wiring for pearson correlation: with values feeds the dataset_1 pin; with values feeds the dataset_2 pin; the number out pin feeds cast to value.
