In addition to stakeholders including managers, employees, creditors, and investors of bankrupt companies, corporate defaults have a ripple effect on the local and national economy. Before the Asian financial crisis, the Korean government only analyzed SMEs and tried to improve the forecasting power...

기업의 부도의 파급효과가 미치는 범위는 어디까지인가? | 기업의 부도는 해당 부도기업의 경영자, 종업원, 채권자, 투자자를 비롯한 이해관계자들 이외에도 지역경제, 국가경제까지 파급효과를 미친다. 아시아 외환위기 발생 전에는 중소기업만을 대상으로 분석을 진행하였고, 다양한 방식의 부도 모형 개발이 아닌, 계량분석 모형 위주로 부도예측모형의 예측력을 높이고자 하였다. | |
빅데이터 기술은 어떤 방향으로 향하고 있는가? | 미래선도기술인 빅데이터 기술은 분석을 비롯하여 인공지능을 넘어 초연결지능화의 방향으로 향하고 있다. 아직 시계열 알고리즘을 통한 기업부도 예측모형 연구는 초기단계임에도 불구하고, 기업부도 예측모형 구축시, 딥러닝 모형이 과거 회귀분석 모형을 이용할 때에 비해 시간을 더욱 단축된다. | |
ANOVA 분석 어떤 4가지 가정이 필요한가? | ANOVA 분석은 4가지 기본 가정이 필요하다. 무작위 추출, 각 집단내 오차의 독립성, 각 집단내 오차는 정규분포를 따름, 모든 집단의 분산은 동일[등분산])하다는 가정이 필요하다. 정규성은 Shapiro(1965)의 정규성 검정으로 진행 가능하다. |
