हम कहते हैं कि मेरे पास 1000 घटक हैं और मैं इस बात पर डेटा एकत्र कर रहा हूं कि ये कितनी बार असफलता का कारण बनते हैं और हर बार असफलता को स्वीकार करने के बाद, मैं इस बात पर भी नजर रख रहा हूं कि समस्या को ठीक करने में मेरी टीम को कितना समय लगा। संक्षेप में, मैं इन 1000 घटकों में से प्रत्येक के लिए मरम्मत के लिए समय (सेकंड में) रिकॉर्ड कर रहा हूं। इस प्रश्न के अंत में डेटा दिया गया है।
मैंने इन सभी मूल्यों को लिया और पैकेज descdist
से उपयोग करके R में एक Cullen और Frey ग्राफ़ को आकर्षित किया fitdistrplus
। मेरी आशा यह समझने की थी कि क्या मरम्मत का समय किसी विशेष वितरण का अनुसरण करता है। यहां boot=500
बूटस्ट्रैप्ड मान प्राप्त करने की साजिश है :
मैं देखता हूं कि यह कथानक मुझे बता रहा है कि अवलोकन बीटा वितरण (या शायद नहीं, किस मामले में, क्या खुलासा कर रहा है?) में आता है, अब यह देखते हुए कि मैं एक सिस्टम आर्किटेक्ट हूं और एक सांख्यिकीविद् नहीं, यह साजिश क्या है? ? (मैं इन परिणामों के पीछे एक व्यावहारिक वास्तविक दुनिया अंतर्ज्ञान की तलाश कर रहा हूं)।

QQplot qqPlot
पैकेज में फ़ंक्शन का उपयोग करते हुए car
। मैंने पहले fitdistr
फ़ंक्शन का उपयोग करके आकार और पैमाने के मापदंडों का अनुमान लगाया ।
> fitdistr(Data$Duration, "weibull")
shape scale
3.783365e-01 5.273310e+03
(6.657644e-03) (3.396456e+02)
फिर, मैंने यह किया:
qqPlot(LB$Duration, distribution="weibull", shape=3.783365e-01, scale=5.273310e+03)
