Bu makalenin amacı Bitlisin 2012-2017 yılları
arasındaki günlük maksimum ve minumum sıcaklıkları arasındaki ilişkiyi Copula
methodu ile açıklamaktır. İlişkiyi açıklamak için çeşitli copula aileleri
kullanılmıştır. Bunlar;
Gumbel, Clayton,
Frank,  Joe, Gaussian ve Survival Claytondur.
Bağımlılık yapısını açıklamak ve
Gumbel, Clayton, Frank,  Joe, Gaussian ve
Survival Clayton copula ailelerinin parametrelerini belirlemek için parametrik olmayan metod olan Kendall
Tau ve Spearman Rho değerleri hesaplanmıştır. Uyum iyiliği testleri Kolmogorov
Smirnov,  Cramer on Mises, maksimum
oalabilirlik metodu, Akaike blgi kriteri ve Bayes bilgi kriteri yardımıyla veri
seti için uygun copula ailesi bulunmuştur. Sonuçlar Bitlisin 2012 yılı ile 2017
yılları arasında günlük maksimum ve minumum sıcaklık değişimleri için güçlü bir
bağımlılık olduğunu göstermiştir.

This
paper aims to examine the relationship between  daily maximum and minimum temperatures of  Bitlis in Turkey between 2012-2017 years with
Copula method. To present the relationship between the variables, we use copula
families such as; Gumbel, Clayton, Frank, 
Joe, Gaussian and Survival Clayton copula.  To explain dependence structures of the data
set and to determine parameters of  Gumbel,
Clayton, Frank,  Joe, Gaussian and
Survival Clayton copula families, we calculate Kendall Tau and Spearman Rho
values which are nonparametric. With he help of  Kolmogorov Smirnov, Cramer Von Mises which are
goodness of  fit test, Maximum likelihood
method, Akaike information Criteria ad Bayes information criteria, we find the
suitable copula family for this data set. 
The results show that there is a strong dependence between daily maximum
and minimum temperatures of Bitlis between 2012-2017 years.
