One of them was selected as an experimental area with five plots of 20 x 20 m. Transformations are performed to search for a new scale in the analyzed variables in such a way that the errors are approximately normally distributed and have homogeneous variances Eisenhart, ; Steel and Torrie, Statistical management of data in population studies of agricultural pests is one of the greatest challenges for researchers dedicated to plant protection; this occurs when they are faced with designing experiments, data analysis, and drawing conclusions.

This deserves special attention because the first transformation is one of those most applied to data from insect populations dstadistica sometimes without verifying a priori and a posteriori the fulfillment of the assumptions.

Results from this analysis allowed selecting the insect larval stage and plant middle stratum as keys to design pest sampling plans. Larvae and adults were quantified at sampling with the help of 10X magnifying glasses. Larvae of the middle stratum were predominant Table 2.

Analyzing data from agricultural pest populations regularly detects that they do not fulfill the theoretical requirements to implement classical ANOVA. The lack of fulfillment of the assumptions for parametric ANOVA and dependence between plant strata and insect stages led to applying the nonparametric Kruskal-Wallis ANOVA test for the previous data combination of both categories.


La tabla siguiente contiene una muestra aleatoria simple de 14 observaciones. Por ejemplo la media muestral. Teniendo en cuenta el intervalo de confianza.

Consideraremos criterios adicionales para seleccionar estimadores. Kruskal-Wallis test, negative binomial distribution, Box-Cox transformations, Thrips palmi, Solanum tuberosum.

The following were the results of the? Modelos lineales y series temporales. Obtendremos, dependiendo de la muestra elegida, las siguientes medias respectivamente: The test of nonparametric multiple comparisons was used when necessary according to Conoverwho proposes using the usual parametric procedure, Fisher’s least significant difference, which is computed on ranks instead of data.

Los valores muestrales X 1The objective of this study was to select the insect stage and the plant stratum of greater predominance as key elements to design sampling plans using data from agricultural pest populations with a negative binomial distribution, and according to the application of non-parametric statistical procedures and seven expressions to transform data.

They have also studied the relationship between these stages and the type of leaf sampled young and old. Parametriva and adult food preferences esttadistica the poinsettia thrips Echinothrips americanus Morgan, Thysanoptera: Siguiendo el mismo proceso que en el caso de la normal el intervalo de confianza resulta.

Ten samplings were carried out in each season.

En la mayor parte de las investigaciones reales suponemos que las variables o transformaciones de las mismas logaritmos, etc, Therefore, the analyses between categories should take into account the combination of both. However, it may affect variance homogeneity mainly when there is a great difference in the number estadistiica observations in the groups or treatments.

Fifteen plants were randomly selected from each plot by following the diagonal. Data transformation With the adjustment of the negative binomial distribution, data were transformed through the estaadistica expressions: Estudiaremos cada uno de los apartados mencionados aunque no necesariamente en el orden en el que aparecen en el cuadro anterior. Utilizaremos la cuasi-varianza muestral como estimador por sus buenas propiedades.

Nevertheless, many researchers do not know that they are subjected to fulfilling theoretical assumptions, such as normality, variance homogeneity, and no correlation between estadistida.

Seven data transformations were tested based on the fit of negative binomial distribution and variance heterogeneity inside the aggregate spatial pattern of this insect species and of the close relationship between the variance and the mean from the fit to the TPL Cabrera, Chapman and Hall, London, UK.
