## Prompt Time

`Given the data points [100, 120, 130, 150, 170, 180, 200, 210, 220, 230, 240, 250, 260, 270, 280, 290, 300, 310, 320, 330], which represent the time-to-failure (in hours) of a piece of industrial equipment, calculate the parameters of the optimal Weibull distribution fitting this data. Then, plot the Weibull probability density function (PDF) along with the data points on the same graph. Please explain the calculus in detail.`

## Response

The Weibull distribution is a continuous probability distribution named after Wallodi Weibull who described it in detail in 1951, although it was first identified by Fréchet (1927) and first applied by Rosin & Rammler (1933) to describe a particle size distribution.

The probability density function (PDF) of a Weibull random variable is:

where:

k>0

*k*>0 is the shape parameterλ>0

*λ*>0 is the scale parameter

The shape parameter, k*k*, determines the shape of the distribution. A value of k<1*k*<1 indicates that the failure rate decreases over time. This happens if there is significant "infant mortality", or early failures. A value of k=1*k*=1 indicates that the failure rate is constant over time. This might suggest random external events are causing mortality, or failure. A value of k>1*k*>1 indicates that the failure rate increases with time. This happens if there is an "aging" process, or parts are more likely to fail as time goes on.

In the case of fitting a Weibull distribution to data, the parameters λ*λ* (scale) and k*k* (shape) are estimated from the data. The most common method of estimating these parameters is the method of maximum likelihood.

The maximum likelihood estimators (MLEs) are the values of the parameters that maximize the likelihood function, which is the joint probability of observing the data given the parameters. For many common distributions, including the Weibull, the MLEs can be calculated analytically by setting the derivative of the likelihood function with respect to the parameters equal to zero and solving for the parameters. However, in practice, this is often done numerically.

In this case, we are using the `FindDistributionParameters`

function in the Wolfram Language to numerically estimate the parameters of the Weibull distribution that maximize the likelihood of observing the given data. This function uses numerical optimization methods to find the parameter values that maximize the likelihood function.

Once we have estimated the parameters of the Weibull distribution, we can plot the PDF of the Weibull distribution along with a histogram of the data to visually assess the fit of the distribution to the data. The histogram is scaled so that it represents a probability density (i.e., the area under the histogram is 1), which allows it to be directly compared to the PDF of the Weibull distribution.

Now, let's proceed with the calculation and plotting.

Used **Wolfram**

The optimal Weibull distribution that fits the given data points has the parameters a=3.9610545463399065*a*=3.9610545463399065 and b=252.55152380832544*b*=252.55152380832544. Here, a*a* is the shape parameter and b*b* is the scale parameter.

Now, let's plot the Weibull probability density function (PDF) along with the data points on the same graph.

Used **Wolfram**

Here is the plot of the Weibull probability density function (PDF) along with the data points on the same graph:

The histogram represents the distribution of your data points, and the red curve is the Weibull PDF with the parameters we calculated. This data set provides a better fit to the Weibull distribution, as you can see from the closer alignment of the data histogram and the Weibull PDF.

In this plot, the x-axis represents the time-to-failure of the equipment, and the y-axis represents the probability density. The red curve shows the Weibull distribution that best fits the data, according to the maximum likelihood estimation of the parameters. The histogram shows the actual distribution of the data points. The closer the red curve is to the shape of the histogram, the better the Weibull distribution fits the data.
