In the current study, momentary time sampling (MTS) and partial-interval recording (PIR) were compared to continuous-duration recording of stereotypy and to the frequency of self-injury during a treatment analysis to determine whether the recording method affected data interpretation. Five previously conducted treatment analysis data sets were ...

What is an example of time sampling? The process may involve fixed time periods (e.g., every 5 minutes) or random time intervals. For example, a researcher may observe a group of children for 10 seconds every 5 minutes for a specific 30-minute period each day, noting the occurrence or nonoccurrence of particular behaviors (overt actions).

Abstract. Recent work on generalized resampled importance sampling (GRIS) enables importance-sampled Monte Carlo integration with random variable weights replacing the usual division by probability density. This enables very flexible spatiotemporal sample reuse, even if neighboring samples (e.g., light paths) have intractable probability densities.

Event sampling is a handy observation technique for observing behaviours in children. It can identify the child's response to certain behaviours, triggers and interactions.

Instead of continuously tracking and recording behavior, observers take periodic samples or snapshots of the behavior at predetermined intervals.

First of all you do not need to resample time line. It is much easier to define time sampling interval variable or sampling frequency variable: T = 0.03; Fs = 1/T; So, x resampling you perform right way: y = resample(x, 1, 2); . But the new time line must be reconstructed via adjusted sampling interval: Ty = T / (1 / 2); ty = (0:length(y)-1)*Ty;The accuracy of momentary time-sampling was evaluated for behaviors occurring for different proportions of time, for different momentary time-samples and for sessions of different lengths. For 1-hr sessions, momentary time-samples of 10, 20 or 30 sec intervals between observations yielded 90% of estimates within 10% of the comparison …
