TruncExp

class braintools.cogtask.TruncExp(mean, min_val=0, max_val=inf, key=None)

Truncated exponential distribution for sampling time durations.

Useful for generating variable-duration phases with exponential distribution truncated to a specified range.

Examples

>>> # Duration sampled from truncated exponential
>>> duration = TruncExp(600*u.ms, 300*u.ms, 1500*u.ms)
>>> Delay(duration)  # Variable delay

>>> # Use in trial_init
>>> def trial_init(ctx):
...     t_delay = TruncExp(600*u.ms, 300*u.ms, 1500*u.ms)
...     ctx['delay_duration'] = t_delay()

max_value()

Truncation upper bound in the sampler’s time unit.

min_value()

Truncation lower bound in the sampler’s time unit.
