Probability Histograms01:17

Probability Histograms

8.6K
A probability histogram is a visual representation of a probability distribution. Similar a typical histogram, the probability histogram consists of contiguous (adjoining) boxes. It has both a horizontal axis and a vertical axis. The horizontal axis is labeled with what the data represents. The vertical axis is labeled with probability. Each rectangular bar in the histogram is 1 unit wide, which suggests that the area under each bar equals the probability, P(x), where x is 1, 2, 3, and so on.

Poisson Probability Distribution01:09

Poisson Probability Distribution

10.0K
A Poisson probability distribution is a discrete probability distribution. It gives the probability of a number of events occurring in a fixed interval of time or space if these events happen at a known average rate and independently of the time since the last event. For example, a book editor might be interested in the number of words spelled incorrectly in a particular book. It might be that, on average, there are five words spelled incorrectly in 100 pages. The interval is 100 pages.

Binomial Probability Distribution01:15

Binomial Probability Distribution

13.0K
A binomial distribution is a probability distribution for a procedure with a fixed number of trials, where each trial can have only two outcomes.
The outcomes of a binomial experiment fit a binomial probability distribution. A statistical experiment can be classified as a binomial experiment if the following conditions are met:
There are a fixed number of trials. Think of trials as repetitions of an experiment. The letter n denotes the number of trials.
There are only two possible outcomes,...

Distributions to Estimate Population Parameter01:26

Distributions to Estimate Population Parameter

4.5K
The accurate values of population parameters such as population proportion, population mean, and population standard deviation (or variance) are usually unknown. These are fixed values that can only be estimated from the data collected from the samples. The estimates of each of these parameters are sample proportion, the sample mean, and sample standard deviation (or variance). To obtain the values of these sample statistics, data are required that have particular distribution and central...

Area of Science:

  • Ecology and conservation biology
  • Wildlife management

Background:

  • Raccoon dogs (Nyctereutes procyonoides) are a protected species in China.
  • Region-wide distribution data for Beijing's raccoon dog population is lacking.
  • Understanding species distribution is crucial for effective conservation.

Purpose of the Study:

  • To assess raccoon dog occurrence patterns and spatial distribution in northeast Beijing.
  • To identify key environmental and anthropogenic factors influencing raccoon dog occupancy.
  • To provide a regional baseline for conservation planning.

Main Methods:

  • Utilized Bayesian occupancy models with camera-trap detection-nondetection data.
  • Analyzed raccoon dog occurrence across environmental gradients.
  • Evaluated the impact of road and human population density.

Main Results:

  • Raccoon dog occupancy probability significantly decreased with higher minor road and human population densities.
  • Species distribution is influenced by avoidance of human-disturbed areas.
  • Higher occupancy was predicted in northern areas and nature reserves, lower in the south.

Conclusions:

  • This study provides the first region-wide assessment of raccoon dog occupancy in northeast Beijing.
  • Anthropogenic factors, particularly human disturbance, are critical for raccoon dog distribution.
  • Findings offer crucial insights for regional conservation and management strategies.
